摘要：
An apparatus and method for generating high-speed clock signals using a voltage-controlled-oscillator (VCO) device. The apparatus implements a linear variable gain amplifier rather than a non-linear hard limiter to remove unwanted signal modulation in VCO output signals. Implementation of the linear variable gain amplifier leads to the generation of amplitude modulation-free oscillation leading to the generation of jitter free high frequency clock signals.
