Abstract
In this paper, the operation of bias current sources at output voltages exceeding BV/sub CEO/ is analysed for various widely used and newly proposed circuit topologies. The most effective way to increase the current mirror output breakdown voltage is based on a feed-back technique. Accurate modelling of the avalanche current factor M up to M-1/spl ap/1 is required to find a good agreement between measurements and circuit simulations.
