Latest Patents

Ching-Yen Chiu's latest patents include an inductive current sensor, a constant peak current circuit, and a DC-DC conversion apparatus. The inductive current sensor is designed for use in a constant peak current circuit of a DC-DC conversion apparatus. It features a sampling unit, a voltage-voltage conversion unit, and an input voltage compensation unit. The sampling unit receives a feedback voltage and an input voltage, generating a sampling voltage that is proportional to the feedback voltage. This feedback voltage is inversely proportional to the inductor current in the DC-DC conversion apparatus. The voltage-voltage conversion unit is connected to the sampling unit, receiving the sampling voltage and input voltage to generate a sensing voltage that is inversely proportional to the sampling voltage. The input voltage compensation unit receives the input voltage to provide an initial voltage level for the sensing voltage, which is proportional to the input voltage.

Another significant patent is a signal conversion device and circuit system that converts a single-ended input voltage into a differential input voltage. This device operates during a sampling phase, a holding phase, and a common-mode voltage generation phase. Capacitors related to the positive and negative input voltages are connected to the single-ended input voltage and a preset voltage, respectively. This design eliminates the need for complex control and reduces the parasitic effects of the circuit.
