Adjustable Signal Generating Device and Related Method for Generating the Adjustable Signal

摘要

An adjustable signal generating device and related method for generating the adjustable signal are described herein. The adjustable signal generating device includes: a voltage generator configured to continuously adjust an output voltage and output the voltage; a &Sgr;&Dgr; modulator configured to output a digital signal of pre-determined-cycle based on the output voltage and a reference voltage; a counter configured to count the number of a target level in the digital signal of a pre-determined number of cycles; and a digital signal generator configured to generate a target signal based on the number of the target level. The described method and device improve the accuracy of the generated signal while remaining the same feel of continuous adjustment.
