Abstract :
Bandpass filters for communications applications are realized using an 80 MHz differential single-stage CMOS operational amplifier and a fully differential identical-resonator elliptic bandpass ladder filter configuration. Experimental results are given for a CMOS sixth-order 260 kHz elliptic bandpass filter with a Q-factor of 40, a clock frequency of 4 MHz, and a power dissipation of 70 mW.
