Latest Patents

One of his latest patents is the "Latch-up mitigated charge pump for high power supply rejection low-dropout regulator." This invention addresses latch-up issues in charge-pump based low dropout (LDO) regulators. It features a high power supply rejection (PSR) low noise architecture that utilizes a latch-up mitigated charge-pump voltage doubler. The design incorporates an N-type metal-oxide-semiconductor field-effect transistor (MOSFET) as a pass transistor, ensuring a very low-noise regulated output voltage suitable for on-chip low jitter oscillators. The control circuitry and power supply timing sequence effectively mitigate latch-up by preventing parasitic diodes from being forward biased.

Another significant patent is the "Inductive-capacitive voltage-controlled oscillator with increased common-mode impedance." This voltage-controlled oscillator (VCO) includes an inductor-capacitor (LC) tank connected to a voltage supply node. It features cross-coupled transistors and a high-frequency current return path, which enhances its performance. The design includes a first decoupling capacitor and a first inductor, which is formed as a conductive trace with a quality factor (Q) value of 25 or greater.
