Programmable gain amplifier
Maturity plannedTargets ASIC (CMOS) onlyDifficulty MediumPriority 1
Resistor or capacitor feedback amplifier with digitally selected gain steps, typically driving an ADC.
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.
