Low Pass Filter, Fully-balance, Gm-CAbstract
In This paper presents a circuit of a fully balanced, current-tunable Gm-C low pass filter (LPF). The proposed circuit is relatively simple and symmetrical with different signals. The filter consists of six bipolar junction transistor (BJT) and one capacitor. The tuning range of the filter’s cutoff frequency is from 1.16 Hz to 413.126 kHz. The filter operates from a supply of 1.5 V. Simulation results using Spice for the proposed reconfigurable LPF are presented.
