Latest Patents

“System Incorporating Power Supply Rejection Circuitry and Related Method” describes a system and method for reducing the effects of power supply variations. One embodiment applies power supply rejection to phase-locked loop (PLL) or delay-locked loop (DLL) circuitry. A first subcircuit filters power from an external source and supplies a modified voltage to a second subcircuit. The design uses a field-effect transistor and a low-pass filter to provide a filtered signal to the transistor’s gate, helping produce a modified supply voltage.

“System, Method and Emulation Circuitry Useful for Adjusting a Characteristic of a Periodic Signal” concerns systems and circuitry for adjusting periodic signals, including signals generated by voltage-controlled oscillators or delay lines. Some embodiments control current through two parallel paths, with an impedance device in one path emulating the impedance characteristics of a device in the other. Alternately switching current between the paths can adjust the signal’s phase or frequency.
