Title: Suneel Arora: Innovator in Voltage Reference Technology
Introduction
Suneel Arora is a notable inventor based in Minneapolis, MN (US). He has made significant contributions to the field of electrical engineering, particularly in the development of voltage reference circuits. With a total of 3 patents to his name, Arora's work has had a substantial impact on the design of devices requiring precise voltage regulation.
Latest Patents
One of Arora's latest patents is a current and temperature compensated voltage reference. This innovative circuit operates with a power supply voltage as low as 1.3 Volts. It utilizes a folded-cascode amplifier to measure temperature-dependent voltages from bias circuits, which include series-coupled diodes or diode-connected bipolar junction transistors (BJTs). The resulting proportional to absolute temperature (PTAT) current is directed through a cascode-protected output transistor. This design creates a PTAT voltage in series with a diode-voltage, ensuring a temperature-compensated voltage reference suitable for implantable cardiac rhythm management systems.
Another significant patent is a voltage regulator designed for battery-powered devices, such as implantable cardiac defibrillators. This regulator provides a stable output voltage, even when large currents are drawn from the battery. It features switches that decouple the regulator from the battery during high current demands, allowing it to receive power from a stable boost output voltage generated by a boost converter. The regulator's design ensures less noise than the boost output voltage, enhancing the performance of the device.
