Chopper-stabilized zero-drift amplifier
Maturity plannedTargets ASIC (CMOS) onlyDifficulty HardPriority 2
Chopper or auto-zero amplifier with ripple reduction for microvolt-level offset and low 1/f noise.
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.
