Latest Patents
John Shi Sun Wei holds a patent for a "Circuit for biasing a transistor and related system and method." This invention includes reference and bias nodes, along with buffer, reference, and feedback stages. The reference node receives a reference current, while the bias node carries a bias signal for coupling to the transistor. The buffer stage effectively isolates the reference node from the bias node. The reference stage generates the bias signal from the reference current, enabling the transistor to conduct a bias current proportional to the reference current. This innovative bias circuit reduces the amplitude and duration of transient overshoot in the bias current of a field-effect transistor during voltage transitions. Additionally, it minimizes discrepancies between predicted and actual bias current values for varying supply voltages.
