Latest Patents

Prasant holds a single patent titled "Circuit for high-resolution phase detection in a digital RF processor." This innovative invention features a novel time-to-digital converter (TDC) that serves as a phase and frequency detector and charge pump replacement in an all-digital Phase-Locked Loop (PLL) within a digital radio processor. The TDC core utilizes a pseudo-differential digital architecture, which ensures its insensitivity to mismatches in NMOS and PMOS transistors. With a remarkable time conversion resolution equating to the propagation delay of an inverter—approximately 20 ps—this technology achieves the finest logic-level regenerative timing in CMOS. Additionally, the TDC is self-calibrating, boasting an estimation accuracy better than 1%. This circuit can also function as a CMOS process strength estimator for analog circuits on large System on Chip (SoC) designs. What stands out further is the integrated power management circuitry, which works to minimize power consumption significantly.
