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.
