Introduction

Tso Min Chen is a notable inventor based in Hsinchu, Taiwan. He has made significant contributions to the fields of audio processing and touch sensing technologies. With a total of 2 patents to his name, Chen continues to push the boundaries of innovation in his industry.

Latest Patents

Chen's latest patents include a "De-pop controller and method thereof" and a "Touch sensing method and associated circuit." The de-pop controller patent describes a system that includes an amplifier and a comparator. The amplifier receives and amplifies an audio input signal, subsequently outputting an audio output signal. The comparator, which is coupled to the amplifier, receives a transient indication signal and compares it with a reference voltage. The result of this comparison is used to control the amplifier's driving ability for de-popping.

The touch sensing method patent outlines a touch control circuit that consists of a first current source, a second current source, multiple switches, a hysteresis comparator, a frequency divider, and a flip-flop. The switches are connected to various external contact points. The hysteresis comparator is linked to two reference comparison voltages. Each external contact point can be selectively connected to the input terminal of the hysteresis comparator through the switches. The first and second current sources generate a sensing voltage, which the hysteresis comparator uses to produce a comparison output that controls the current sources.
