Abstract

A receiver coil of an inductive angular position sensor can have circuit features that become smaller than reasonable for high resolution measurement designs. This is especially true when multiple receiver coils are used, such as in a three-phase configuration, and when each of the multiple receiver coils is in a twisted loop configuration. The disclosed inductive angular position sensor utilizes different spatial frequencies for a rotor coil and the receiver coils. For example, the spatial frequency of the receiver coils may be kept smaller than the rotor coil. In this condition, the fundamental frequency of the angular position sensor is shifted to the least common multiple of the spatial frequencies, making the angular resolution of the inductive angular position sensor high, while the circuit features of the receiver coils are maintained at a reasonable size.

Abstract

A multi-phase power system configured to add and remove phases according to a plurality of states can increase the efficiency of the power system, which can increase a battery life in mobile applications. After phases are shed, a load may quickly change requiring all phases to be activated before an over current protection triggers a shutdown. The response of the power system to these load transients may be improved through the use of multiple triggers, which can provide an early warning of the changing load requirements more accurately and consistently than a single trigger.

Abstract

A multiphase power stage that includes addressing and communication techniques to read temperatures of the phases for thermal load balancing is disclosed. The disclosure describes driver modules that can be assigned addresses for serial communication on a common communication bus by temporarily communicating the addresses over dedicated pulse width modulation connections between the driver modules and the controller. After assignment, a temperature request message, addressed to a driver module, can trigger the driver module to transmit an analog temperature signal to a common temperature bus coupled between the driver modules and the controller. The temperatures of the driver modules may be collected in order to activate and deactivate driver modules based on their temperatures, which can balance a thermal load on the multiphase power stage.

Abstract

Devices and methods are disclosed for high power inverter modules (100) with enhanced thermal and mechanical performance, for use in electric vehicles. The disclosed devices feature enlarged clips (108) that cover an entire die (104), to distribute mechanical forces, thus preventing die cracks for improved reliability. In these power modules, semiconductor dies (104) are sandwiched between a three-layer direct bond metal (DBM) structure (102) and the enlarged clip. A pre-molded clip assembly (105) can be used that includes integrated metalliization (107) to eliminate the need for external wire bonds. Alternatively, semiconductor dies (104) can be inverted in a flip-chip configuration (701) to face a modified DBM structure (702) that integrates the metallization (707). Simulations of the disclosed power inverters indicate improved efficiency in dissipating heat.

Abstract

A switching regulator is disclosed that includes a driver having a driver-wake circuit configured to report its readiness for operation during a startup period. The driver-wake circuit can operate during startup by temporarily drawing power from the controller's power supply until the driver's power supply has reached a level sufficient to power the driver-wake circuit. The driver-wake circuit is configured to communicate the status of the driver's power supply during startup over a pin typically used to communicate temperature. Thus, the disclosed driver can communicate status during startup without needing extra pins, and because the circuitry is automatically disconnected after startup, very little additional power is consumed.

Abstract

An image sensor may perform hybrid pixel binning. In pixel binning, pixel values from multiple pixels are combined into a single representative binning value. In a hybrid pixel binning scheme, different pixel groups may be binned in different ways in a single image sensor. When the range of values in a pixel group is low (indicating a flat surface), a mean or median binning scheme may be used. When the range of values in a pixel group is high (indicating an edge), a spatial weighting binning scheme may be used. When a pixel group has an intermediate range, a blend of the median/mean and spatial weighting may be used to avoid undesired blinking in the binning output. The hybrid binning scheme may reduce noise while still preserving high-frequency detail.

Abstract

An image sensor may include an array of pixels arranged in rows and columns. Each pixel can include a subpixel circuit and one or more subtraction circuits. Each subpixel circuit can be selectively coupled to neighboring subpixel circuits in the same row via horizontal odd and even switches and can be selectively coupled to neighboring subpixel circuits in the same column via vertical odd and even switches. The horizontal and vertical switches can be turned on in separate phases to store difference values from pairs of neighboring subpixels into the one or more subtraction circuits. The difference values can be read out using comparators and one or more shift registers to output an edge image that includes only edge information.
