000121024 5203_ $$aIn this letter, a fully integrated configurable front-end for Impedance Spectroscopy (IS) is presented. The circuit includes fully differential in-phase and quadrature channels, using a transconductor (TC)-transimpedance (TI) approach. The input TC, shared for both channels, is based on a programmable degenerated differential pair to attain low-noise programmable-gain, while identical TII/Q with embedded synchronous rectification provide both I, Q outputs, filtered through fc adjustable Gm-C integrators. It exhibits a programmable gain ranging from 0 dB to 40 dB with 87 MHz bandwidth, amplitude and phase recovery errors below 1.9% and 2.5∘ respectively and an input referred noise floor of 16.7 nV/Hz. The result is a high-performance very compact topology with a total power consumption of 292 μW at a 1.8 V power supply, thus constituting an appropriate solution for full on chip multichannel IS systems.
