An internal voltage line doubles as a shield for the sensing voltage line, improving noise immunity and stabilizing compensated voltages.
Independent capacitive and inductive channels let an isolated gate driver transmit signals across the barrier with fault detection for ASIL compliance.
Internal timing adjustment and oscillator self-diagnosis let this window watchdog timer monitor microcomputer clear intervals without external components.
Delayed self-correlation detects UWB pulses under distortion without extra reference pulses, cutting energy use and system complexity.
Cross-coupled capacitive elements offset transistor Cgd, widening active inductor peaking range and boosting signal swing or lowering power.
Back-bias generation and high-impedance gain stages help capacitive sensors achieve low-noise, low-current signal buffering.
