Realization of Fully Controllable Negative Inductance with Single Operational Transresistance Amplifier

Abstract

A grounded negative inductance emulator is proposed with full independent control on both the inductance value and the condition. It uses a single operational transresistance amplifier (OTRA), a capacitor, and five resistors, two of which are for independent control. Experimental results, which confirm the theoretical analysis, are presented.

Design of operational transresistance amplifier based grounded active inductor and implementation of bandpass filter

“…A number of grounded immittance OTRA topologies are described in [7,1]. The strategy for realizing a negative grounded active inductor is demonstrated in [8,1]. This article is organized as: the basic OTRA cell is introduced in II, the OTRA grounded inductor is designed in III.…”

Single OTRA Based Analog Multiplier and Its Applications

“…Recently the OTRA has emerged as an alternate analog building block [13][14][15][16][17][18][19][20][21][22][23][24][25][26] which inherits all the advantages of current mode techniques. The OTRA is a high gain current input voltage output device.…”

“…Several high performance CMOS OTRA topologies have been proposed in the literature [13][14][15][16]. In the recent past OTRA has been extensively used as an analog building block for realizing a number of analog signal processing [17][18][19][20][21] and generation circuits [22][23][24]. This paper presents a single OTRA based low voltage analog multiplier which does not use any external passive components and hence is suitable for integration.…”

New Topologies of Lossless Grounded Inductor Using OTRA

“…Several high-performance CMOS OTRA topologies have been proposed in literature [1][2][3][4] leading to growing interest in OTRA-based analog signal processing circuits. In the recent past OTRA has been extensively used as an analog building block for realizing a number of signal processing circuits such as filters [5][6][7][8], oscillators [9,10], multivibrators [11,12], and immittance simulation circuits [9,[13][14][15], an application which has been dealt with in this paper. A number of grounded parallel immittance topologies using single OTRA are proposed in [13].…”

“…However none of these configurations can realize a lossless grounded inductor. The structure in [14] presents simulation of lossless negative grounded inductance. Lossless grounded inductor simulators using two OTRAs, five resistors, and one capacitor are presented in [9,15].…”
