摘要: A digitally controlled balanced output transconductor (DCBOTA) is proposed and analyzed. The DCBOTA based on the BOTA given MOS switches. transconductance tunable in a range of 2/sup n-1/ times using n bits control word. wide band variable gain amplifier (DCVGA) six order lowpass filter are presented. has advantage independent cutoff frequency. Simulations results included to verify analysis.
