| Abstract: | The theoretical background and a selection of simulated results are presented for a 10?µA PTAT current generator that is a modified CMOS version of an existing bipolar configuration. Using standard 0.35?µm CMOS technology, the circuit exhibits a current variation of less than 0.01% when the supply rail voltage is changed from 0.5 to 10?V. |
