Abstract
A semiconductor integrated oscillator circuit requiring higher impedances than are practical by integrated circuit technology and generally provided by discrete components external to the circuit are functionally provided in the integrated circuit by a "current mirror" circuit which provides the bias function separate from the signal function.
