In this paper, we present a new impedance measurement integrated circuit (IC) for achieving a wideband coverage up to 10 MHz and low power consumption. A frequency-shift technique is applied to down-shift the input frequency, which ranges from 100 kH

We present an impedance-monitoring IC achieving a wide frequency range (FR) and fast output data rate (ODR). The proposed IC support a wide FR with improved spectral density by down-converting the signal to the intermediate frequency (f IF ) in front
