Title: Innovations by James Ho

Introduction

James Ho is an accomplished inventor based in San Jose, California. He has made significant contributions to the field of electrical engineering, particularly in the development of charge pumps and voltage detection systems. With a total of two patents to his name, Ho continues to push the boundaries of innovation in his industry.

Latest Patents

One of Ho's latest patents is focused on a low power charge pump. This charge pump is designed to control current flow at an output node in response to input signals. A plurality of control signals are generated based on these input signals, which operate to manage the timing and duration of current flows within the charge pump, ultimately reducing power consumption. The design allows for the conductivity of a first path between a power supply and the output node, as well as a second path between the output node and ground potential, to be varied. Additionally, this charge pump can be integrated into a phase-locked loop (PLL), where the input signals are produced by a phase/frequency detector, and the current flow at the output node controls an oscillator element.

Another notable patent by Ho involves the detection of a closed-loop voltage. This voltage detector includes first and second transistors that deliver first and second currents to high impedance nodes. It also features third and fourth transistors that draw third and fourth currents from these nodes. The first and second currents are scaled replicas of a current flowing through a current source of a voltage-to-current converter, which converts the closed-loop voltage to a current. This innovative design enhances the accuracy and reliability of voltage detection in various applications.
