摘要：

This paper describes a novel operational amplifier (OPA) voltage controlled oscillator (VCO) circuit which can be used in frequency range exceeding unity gain bandwidth. The VCO topology is based on the operational-amplifier- negative-inductance converter. The oscillator architecture, mathematical modeling, simulation and measurement results are presented. The designed VCO uses an ultra low noise wideband OPA LMH6624, covers frequency band between 786.3 MHz and 1.0 GHz and exhibits a maximum in-band phase noise of - 141.3 dBc/Hz at 1 MHz offset from carrier frequency. Power consumption of the VCO core is 57 mW from a +/- 2.5 V power supply. The simulation results are verified by implementing the oscillator that generates a low-noise signal.
