2-10 MHz programmable continuous-time 0.05 degrees equiripple linear phase filter

The authors present a bipolar monolithic seventh-order 0.05 degrees equiripple linear phase transconductance-capacitor lowpass filter with a cutoff frequency (f/sub c/) tunable between 2 and 10 MHz. Programmable equalization up to 9 dB at f/sub c/ is also provided. Total harmonic distortion at 2 V/sub pp/ is less than 1%. Nominal power consumption from a single 5-V supply is 135 mW. The circuit also has a low power mode (<5 mW dissipation).<
