A digital frequency and Q tuning technique is proposed for low-voltage (1 V) active RC biquad filters that uses programmable capacitor arrays (PCAs). The proposed technique does not require any peak detectors, which are difficult to implement at low voltages. Instead, it uses a small number of analogue comparators, a digital comparator and binary counters to adjust the PCAs
