Latest Patents

One of his latest patents is titled "Self biased low noise high PSRR constant gm for VCO." This invention presents a system and method for voltage-controlled oscillator (VCO) biasing in low voltage circuits, particularly focusing on low resistance elements that are highly susceptible to noise. In this embodiment, a poly resistor and triode resistor are utilized to counteract the effects of temperature variations on the circuit. The triode resistor is powered by a voltage source that employs a pair of diodes coupled to a constant transconductance (gm) circuit, generating a reduced noise voltage that remains independent of power supply noise. The sizes of the triode and poly resistors can be adjusted as needed.

Another significant patent is for a "Wireless receiver applicable to multiple coexisting positioning systems." This wireless receiver is designed to receive various co-existing wireless signals from different positioning systems. It includes an analog frontend and an analog-to-digital converting unit. The analog frontend converts bands of the co-existing wireless signals into corresponding intermediate bands using a local frequency, providing an intermediate signal that includes these bands. The analog-to-digital converting unit is connected to the analog frontend and converts the intermediate signal into a digital signal, ensuring that its operation band covers the multiple intermediate bands.
