Title: Shu-Han Nien: Innovator in Duty Cycle Correction and Bandgap Reference Circuits
Introduction
Shu-Han Nien is a prominent inventor based in Changhua, Taiwan. He has made significant contributions to the field of electronics, particularly in the development of innovative circuits. With a total of 3 patents to his name, Nien continues to push the boundaries of technology.
Latest Patents
One of Nien's latest patents is a duty cycle correction apparatus. This invention illustrates a method for fast adjusting internal clocks to achieve specific duty cycles. The process begins with adjusting a reference clock to a specific duty cycle based on analog feedback clocks. A phase detector then compares the phases of the reference clock and an internal clock, generating a phase detection signal. Using a digital-analog converter, complementary signals are produced according to the phase detection signal, which are then utilized to adjust the duty cycles of the internal clocks. When the duty cycle of the internal clock matches the specific duty cycle, the codes of the complementary signals are recorded.
Another notable patent is the bandgap reference circuit. This circuit incorporates multiple current sources, an operational amplifier, a voltage divider, and bipolar transistors. The second bipolar transistor receives a first voltage from the voltage divider, while the third bipolar transistor receives a second voltage. A first resistor connects the third current source to the third bipolar transistor, facilitating the operation of the circuit.
