A Transimpedance Amplifier for Remotely Located Quartz Tuning Forks    [PDF]

Ethan Kleinbaum, Gabor Csathy
The cable capacitance in cryogenic and high vacuum applications of quartz tuning forks imposes severe constraints on the bandwidth and noise performance of the measurement. We present a single stage low noise transimpedance amplifier with a bandwidth exceeding 1 MHz and provide an in-depth analysis of the dependence of the amplifier parameters on the cable capacitance.
