BIAS-LESS TECHNIQUE FOR DESIGN OF A DIGITAL LINEAR VOLTAGE REGULATOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240329677 titled 'BIAS-LESS TECHNIQUE FOR DESIGN OF A DIGITAL LINEAR VOLTAGE REGULATOR
Abstract: Embodiments herein relate to a digital linear voltage regulator (DLVR). The DLVR includes a set of power links, each containing multiple columns of power transistors that can be individually turned on or off based on digital data from a main control circuit. Additionally, individual power links can be turned on or off based on monitoring the dropout voltage of the power links and the drain-to-source resistance (Rds_on) of replica columns. Monitoring compensates for changes in Rds_on due to variations in the input voltage (Vin) to prevent unstable behavior. The DLVR eliminates the need for dynamic biasing of control gate voltages, reducing complexity and power losses.
Key Features and Innovation:
- DLVR includes power links with multiple columns of power transistors that can be individually controlled.
- Power links can be turned on or off based on digital data from a main control circuit.
- Monitoring of dropout voltage and Rds_on of replica columns allows for individual power link control.
- Compensation for changes in Rds_on due to input voltage variations prevents unstable behavior.
- Eliminates the need for dynamic biasing of control gate voltages, reducing complexity and power losses.
Potential Applications: - Power management systems - Voltage regulation in electronic devices - Battery charging systems - Renewable energy systems
Problems Solved: - Unstable behavior due to changes in Rds_on - Complex control gate voltage biasing - Power losses in voltage regulation systems
Benefits: - Improved stability in voltage regulation - Simplified control circuitry - Reduced power losses - Enhanced efficiency in power management
Commercial Applications: Title: Digital Linear Voltage Regulator for Efficient Power Management This technology can be applied in various industries such as consumer electronics, automotive, renewable energy, and telecommunications for efficient power management and voltage regulation.
Questions about DLVR: 1. How does the DLVR compensate for changes in Rds_on due to input voltage variations? The DLVR monitors the dropout voltage and Rds_on of replica columns to adjust individual power links, ensuring stable behavior despite input voltage changes.
2. What are the potential commercial applications of the DLVR technology? The DLVR can be used in consumer electronics, automotive systems, renewable energy applications, and telecommunications for efficient power management and voltage regulation.
Original Abstract Submitted
embodiments herein relate to a digital linear voltage regulator (dlvr). the dlvr includes a set of power links which each includes many columns of power transistors. the columns can be turned on or off individually based on digital data from a main control circuit. additionally, individual power links can be turned on or off based on monitoring of a dropout voltage of the set of power links and a drain-to-source resistance, rds_on, of replica columns. an input voltage may be monitored as an alternative. the monitoring compensates for changes in rds_on due to changes in an input voltage, vin, which could otherwise result in unstable behavior. the dlvr can avoid the complexity and power losses of dynamic biasing of the control gate voltages of the transistors.
