چکیده

A simple and novel design for a current comparator is proposed. The proposed current comparator utilizes the concept of adjustment of switching threshold voltage of an inverter employed in the circuit design to develop a reference current for the purpose of current comparison. The proposed circuit was simulated using 0.18 μm TSMC CMOS technology and satisfactory results were obtained.

An 11-Bit Single-Ended SAR ADC with an Inverter-Based Comparator for Design Automation

This paper proposes a low power single-ended successive approximation register (SAR) analog-to-digital converter (ADC) to replace the only analog active circuit, the comparator, with a digital circuit, which is an inverter-based comparator. The replacement helps possible design automation. The inverter threshold voltage variation impact is minimal because an SAR ADC has only one comparator, and...

Different Methods for Direct Torque Control of Induction Motor Fed From Current Source Inverter

Two different methods for direct torque control (DTC) of induction motor fed from current source inverter (CSI) is analyzed in the paper. The first one is derived from well-known DTC strategy developed for voltage inverter drives. This type of control basically uses hysteresis type controllers for torque and flux. In CSI drive there is only one controller used for torque control loop. The probl...

Direct Torque Control for Three-Level Neutral Point Clamped Inverter-Fed Induction Motor Drive

Direct torque control (DTC) is a control technique in AC drive systems to obtain high performance torque control. The classical DTC drive contains a pair of hysteresis comparators and suffers from variable switching frequency and high torque ripple. These problems can be solved by using space vector depending on the reference torque and flux. In this paper the space vector modulation technique ...

A New Approach to Design Low Power Cmos Flash A/d Converter

In the present paper, a 4-bit flash analog to digital converter for low power SoC application is presented. CMOS inverter has been used as a comparator and by adjusting the ratio of channel width and length, the switching threshold of the CMOS inverter is varied to detect the input analog signal. The simulation results show that this proposed 4-bit flash ADC consumes about 12.4 mW at 200M sampl...
