MEMS microphone front end
Maturity plannedTargets ASIC (CMOS) onlyDifficulty HardPriority 2
Capacitive microphone bias charge pump, high-impedance preamplifier and delta-sigma modulator producing a PDM stream.
Planned. This block is specified in the catalog with its interfaces and targets. No implementation exists yet; the skeleton command below generates a lint-clean shell with its ports and registers.
