We present a widely tunable transimpedance amplifier (TIA) with a dc servo loop and an optional bandwidth extension. All resistors are implemented as multi-element pseudo-resistors, which feature high linearity, robustness against process and temperature, and a very wide tuning range of more than five decades. The TIA features a noise floor of 0.6fA/sqrt(Hz) at its maximum transimpedance of 150GOhm and a bandwidth of 2.9MHz at its minimum transimpedance of 440kOhm. A subsequent inverting amplifier stage provides an optional pole-zero compensation to extend the TIA's overall bandwidth. An additional dc servo loop can be used to compensate large dc currents.
