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.
