Zusammenfassung:	A microcircuit bias-current supply in a wristwatch-pager. An FM-radio receiver in a microcircuit paging device operates intermittently with a short on-time and long off-time to reduce power consumption and preserve battery life. Ths bias-supply circuit distributes predetermined bias currents to a plurality of functional circuit areas of the microcircuit die, the bias currents being disabled during off-time of the receiver such that the current drain of the entire microcircuit is virtually zero, being in the range of nanoamps. The inefficiencies and disadvantages of a series switch to switch power on and off are eliminated by providing a plurality of switched current sources which perform the dual function of circuit biasing and current switching.
