15 to 2780 kHz amplifier with band-pass filter

Overview

Band-pass filter (BPF) includes LPF and two stages amplifier. All stages input DC are decoupled and compensated. LPF is based on Chebyshev 4th stage filter. BPF has constant gain 20 dB. Two stage amplifier gain is changed by digital code from 0 to 60 dB.
