Study of Small-signal Model of Simple CMOS Amplifier with Instability Compensation of Positive Feedback Loop
(De Gruyter Open, 2015-07-06)
The paper deals with precise analysis of simple AC variable gain CMOS amplifier. The circuit can be used as a simple voltage follower (6 MOS transistors are required) or amplifier. The main attention of this work is focused ...
Simple Oscillator with Enlarged Tunability Range Based on ECCII and VGA Utilizing Commercially Available Analog Multiplier
(De Gruyter, 2016-04-07)
This work presents an example of implementation of electronically controllable features to an originally unsuitable circuit structure of oscillator. Basic structure does not allow any electronic control and has mutually ...
Novel first-order all-pass filter applications of z-copy voltage differencing current conveyor
(NISCAIR ONLINE PERIODICALS REPOSITORY (NOPR), 2015-08-05)
The application of z-copy voltage differencing current conveyor (ZC-VDCC) in simple and interesting first-order all-pass sections has been studied in the present paper. The solutions presented here have presumptions for ...
An Additional Approach to Model Current Followers and Amplifiers with Electronically Controllable Parameters from Commercially Available ICs
Several behavioral models of current active elements for experimental purposes are introduced in this paper. These models are based on commercially available devices. They are suitable for experimental tests of current- ...
Behavioral model for emulation of ZC-CG-VDCC
(The Institute of Electronics, Information and Communication Engineers (IEICE), 2016-01-29)
This paper presents a proposal and an experimental analysis of behavioral emulator of so-called z-copy controlled-gain voltage differencing current conveyor (ZC-CG-VDCC) based on commercially available devices. Most of ...
