Abstract:
A multiple operating-mode comparator system can be useful for high bandwidth and low power automated testing. The system can include a gain stage configured to drive a high impedance input of a comparator output stage, wherein the gain stage includes a differential switching stage coupled to an adjustable impedance circuit, and an impedance magnitude characteristic of the adjustable impedance circuit corresponds to a bandwidth characteristic of the gain stage. The comparator output stage can include a buffer circuit coupled to a low impedance comparator output node. The buffer circuit can provide a reference voltage for a switched output signal at the output node in a higher speed mode, and the buffer circuit can provide the switched output signal at the output node in a lower power mode.

Application number: 17/380,601

Abstract:
Microelectromechanical system (MEMS) accelerometers are described. The MEMS accelerometers may include multiple proof mass portions collectively forming one proof mass. The entirety of the proof mass may contribute to detection of in-plane acceleration and out-of-plane acceleration. The MEMS accelerometers may detect in-plane and out-of-plane acceleration in a differential fashion. In response to out-of-plane accelerations, some MEMS accelerometers may experience butterfly modes, where one proof mass portion rotates counterclockwise relative to an axis while at the same time another proof mass portion rotates clockwise relative to the same axis. In response to in-plane acceleration, the proof mass portions may experience common translational modes, where the proof mass portions move in the plane along the same direction.
