Title: The Innovative Contributions of Sang Ton Ngo

Introduction

Sang Ton Ngo is a notable inventor based in San Jose, California. He has made significant contributions to the field of electrical engineering, particularly in the development of circuits and methods for actuator calibration and charge pump circuits. With a total of four patents to his name, Ngo's work has had a considerable impact on the industry.

Latest Patents

One of his latest patents is titled "Circuits and methods for calibrating actuator displacement." This invention includes circuits and methods designed to calibrate position displacement in a voltage-controlled actuator. The calibration circuit features an actuator with a control terminal that receives a programmable control voltage to set a displacement. It also includes a switch that selectively decouples the programmable voltage from the control terminal and couples a reference current when decoupled. A comparator senses the voltage difference between the control voltage and the control terminal, while a timer measures the time required to increase the control terminal voltage. This innovation allows for the determination of the actuator's capacitance, which is essential for accurate position calibration.

Another significant patent by Ngo is related to "Charge pump circuits and methods." This invention involves a first charge pump that receives a voltage and generates an output voltage and current to meet the power requirements of a circuit. A second charge pump is coupled in series with the first, generating a different output voltage and current for varying power needs. This design allows for efficient power distribution within electronic circuits.
