摘要: In this paper, a new current-mode second-order differential type Class-AB log-domain notch filter is proposed. It systematically designed using state-space synthesis method. The circuit current-mode, and type. the circuit, input output values, dominant variables are all currents. Input currents also signals. Only transistors grounded capacitors required to realize circuit. Three cases of were obtained. regular was obtained when omegan=omega0, low-pass omegan>omega0, high-pass omegan>omega0. center frequency, quality factor, gain can be electronically tuned by changing external Time frequency-domain simulations performed PSPICE program for verify theory show performance it. For purpose, simulated idealized bipolar junction transistor models AT&T CBIC-R (NR200N-2X NPN), (PR200N-2X PNP) transistors.
