Chopper Modulation Improves OTA Information Transmission
We have investigated information transmission in operational transconductance amplifiers (OTA) using chopper modulation. Previous work showed that the optimal frequency bandwidth for an OTA was much higher than typical operating frequencies. Here we analyze the information transfer rates for a folded cascode amplifier and a chopper modulated folded cascode amplifier using the principles of information […]
Evaluation of AC VRM Topologies for High-Frequency Power Distribution Systems
In this paper is shown that the regulated series resonant rectifier (SRR) and series-parallel resonant rectifier (SPRR) with variable resonant capacitance are good candidates for ac voltage regulator modules (VRMs) in high-frequency power distribution systems with a sinusoidal ac bus. Control characteristics of the SRR and SPRR are derived using the sinusoidal approximation method. The […]
Micro controller Based Multi phase Sequence Detection System
The report describes various methods for determining the phase sequence of a multiphase system. The reference phase is chosen random from the multi-phase and is assigned the serial number 1. Then with the help of a general rule and a micro controller, the serial number of any other phase is determined. The discussion starts with […]
