Abstract:

In this paper, we present an instrumentation amplifier for high speed electrical impedance tomography. The instrumentation amplifier includes a fast acting automatic gain control, which allows it to process a wide dynamic range of input signals with low power consumption and without sacrificing the frame rate of the tomography system. The instrumentation amplifier was designed in a 3.3 V, 180 nm CMOS process. Simulation results show that it has a dynamic range of 85 dB over a 10 MHz bandwidth, with a total power consumption of 3.1 mW.
