Introduction

Cheng-Dao Su is a notable inventor based in Hsinchu County, Taiwan. He has made significant contributions to the field of electronics, particularly in the development of advanced oscillators. With a total of 2 patents, his work showcases innovative solutions that address various challenges in signal generation.

Latest Patents

One of his latest patents is a voltage controlled oscillator. This invention includes a current controlled oscillator, a voltage to current conversion circuit, and a noise cancellation circuit. The current controlled oscillator is designed to receive a bias current and generate an oscillating signal with a frequency that corresponds to the bias current. The voltage to current conversion circuit is connected to a power supply voltage and is responsible for generating a supply current based on an input voltage. Additionally, the noise cancellation circuit receives a bias voltage and the supply current, generating a noise cancellation current to counteract variations in power supply voltage, ultimately refining the bias current.

Another significant patent is the inductor-less local oscillator generation apparatus. This device is engineered to produce one or more output signals that minimize frequency pulling effects. The apparatus consists of a multi-phase signal generation circuit, a phase signal generation circuit, and one or more output circuits. The multi-phase signal generation circuit takes an input clock signal with a specific frequency and generates a multi-phase clock signal. This signal comprises several clock signals, each maintaining the same frequency but differing in phase. The phase signal generation circuit processes the multi-phase clock signal to output various phase signals, while the output circuits generate the output signals based on the clock and phase signals without feedback from the output signals.
