Abstract
—A readout circuit for the measurement of amperometric sensors is presented. The circuit consists of analog frontend (AFE) and an automatic gain adjustment circuit to tune the gain of the AFE according to the input current covering a wide dynamic range of 169dB and a minimum input referred noise of 44 fA. The circuit is implemented in 0.35 µm technology, consumes 5.83 mW from 3.3 V supply voltage and occupies 0.31 mm2 silicon area.
