Programmable Regulator Voltage Controlled Ring Oscillator - A simplified explanation of the abstract

This abstract first appeared for US patent application 18366742 titled 'Programmable Regulator Voltage Controlled Ring Oscillator

Simplified Explanation

The patent application describes a system for aligning the phase of a ring oscillator and reducing jitter.

The system includes a resistor bank array, an operational amplifier, transistors, and a realignment circuit.
The resistor bank array generates a signal, and the operational amplifier compares this signal with a voltage from a PLL circuit.
A transistor is used to control the frequency of the ring oscillator during a realignment state.
The realignment circuit generates a signal to align the ring oscillator with a clock signal.

Original Abstract Submitted

Systems, devices, and methods are described herein for aligning a phase of a ring oscillator and removing jitter. An oscillator includes a resistor bank array, an operational amplifier, a first and second transistor, and a realignment circuit. The resistor bank array has a plurality of resistors configured to generate a first signal. The operational amplifier is coupled to a PLL circuit and is configured to compare a voltage of the PLL circuit with a voltage of the resistor bank array. The first transistor is coupled between the operational amplifier and a ring oscillator. The first transistor is configured to generate a second signal to control a frequency of the ring oscillator during a realignment state. The realignment circuit is coupled to the first transistor and the ring oscillator. The realignment circuit is configured to generate a realignment signal to align the ring oscillator with a first clock signal.
