Abstract: An electronic circuit, such as the type which may be found in a watch pager receiver, which contains both analog and digital circuitry, includes harmonic noise minimization circuitry. The minimization circuitry is constructed using standard cell designs which are optimized for particular clock operations. Select circuit components are optimized to produce minimal harmonics, to operate at the predetermined frequency and include resistance means to provide an output of a second known level which is characterized by an optimized output signal having a ramped wave configuration. The optimized output signal is of adequate strength to provide an input to a downstream component.

Abstract: 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. The 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 stitch 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.
