Abstract :
A circuit with a transfer function Iout=c/Iin (1/x circuit) with MOSFETs biased in weak inversion is presented. The circuit operates at a supply voltage that is a few hundred millivolts above one threshold voltage. The accuracy is +4%/-8% with respect to the desired transfer over a 6 pA to 2 nA input current range
