Abstract :
In this paper, we describe an automatic tuning scheme for G/sub m/-C filters. It employs an integrator as master rather than commonly used VCO (Voltage Controlled Oscillator) or VCF (Voltage Controlled Filter). This proposed tuning scheme is implemented into a +/-1.5 V 10 mW 4 MHz 5-th order elliptic low-pass filter.
