摘要： This document discusses, among other things, apparatus and methods for an edge rate driver for a power converter switch. In an example, the driver can include an input node configured to receive a pulse width modulated signal, a first switch configured to couple a control node of the power converter switch to a supply voltage during a first state, a second switch configured to couple the control node of the power converter switch to a reference voltage during a second state, and a first current source configured to supply charge current to the first switch when the power converter switch transitions from the second state to the first state, the charge current configured to charge a parasitic capacitance of the power converter switch.

摘要： This application discusses simplified interface circuits for a gyroscope. In an example, an interface can include an automatic gain control (AGC) circuit configured to couple to driver for a proof mass of a gyroscope sensor and to drive the proof-mass to oscillate at a predefined oscillation amplitude, and a phase-locked loop (PLL) configured to receive sensed oscillation information from the proof-mass and to provide at least a first phase signal synchronized with a sinusoidal waveform of the sensed oscillation information.

摘要： This document discusses, among other things, circuits and methods for providing an indication of an impedance between a detecting pin and a first signal pin of an audio socket using first and second comparators to, among other things, determine if moisture is present in the audio socket. If moisture is present in the audio socket, communication between an audio processing unit and the audio socket can be disabled.
