Latest Patents

One of his significant patents is titled "Differential integrator having offset and gain compensation." This invention discloses a fully differential switched-capacitor integrator that accepts a single-ended or unbalanced input signal. It compensates for the offset and finite gain of the operational amplifier without requiring an extra converter circuit. The proposed circuit utilizes a special input structure that incorporates capacitors to store the offset and low-frequency noise of the operational amplifier. A preferred embodiment of this invention implements the switching means as transmission gates using CMOS transistors. Additionally, clock feedthrough is prevented by providing two non-overlapping clock phases with a delayed clock each, thus avoiding clock feed-through. This invention offers a promising alternative for applications such as low noise filters and sigma delta modulators. Lee Tay Chew holds 1 patent.
