Abstract :
A compact subthreshold ISFET readout circuit configured in source follower topology is presented. This ISFET readout circuit configuration can convey linear pH response from 4 to 10 with constant 1 nW power consumption at 1 V supply. Negative temperature gradient of this readout circuit is determined and confirmed with the simulation results.
