Switch timing resets parasitic capacitor voltage in duty-cycled resistor feedback paths, reducing noise and preserving signal accuracy.
Pre-matching driver supply levels and filtering modulation-index changes suppress ASK pulse overshoot and undershoot across RFID and NFC loads.
A programmable DAC and op-amp bias feedback loop enables RF output steps below 0.5 dB while maintaining stability across temperature and supply variation.
Closed-loop DAC and op-amp feedback enables RF power steps below 0.5 dB while maintaining temperature and supply-voltage stability.
