Abstract

A bipolar seventh-order 0.05° equiripple linear phase (constant group delay) transconductance-capacitor (g_m-C) low-pass filter with a cutoff frequency (f_c) tunable between 2 and 10 MHz is presented. Programmable equalization up to 9 dB at f_c is also provided. Total harmonic distortion at 2 V_p-p is less than 1%, with a dynamic range equal to 49 dB. Nominal power consumption from a single 5-V supply is 135 mW. The circuit also has a low-power mode (<0.5-mW dissipation)
