Title:
【発明の名称】自動電流制御を備えた電圧制御発振器
Document Type and Number:
Japanese Patent JPH04505533
Kind Code:
A
Abstract:
An automatic voltage-controlled oscillator (VCO) current control circuit, that senses a voltage in the VCO representative of the current of the VCO, compares that voltage to a reference voltage, and applies the voltage resulting from that comparison back to the VCO at a point therein that changes its bias state in such a manner as to maintain the noise level in the VCO at a minimum and also maintains the power output of the oscillator substantially constant.
