Design of Self-tracking High-pass Filter

Design of Self-tracking High-pass Filter

A novel self-tracking high-pass filter by using analog multiplier and current feedback op-Amp (CFA) is proposed in this paper. The frequency-voltage (F/V) converter transforms the input pulse signal into the voltage, and then the output of F/V converter controls the cut-off frequency of voltage cont...
