“…A novel feature of the proposed band-pass filter is that all the three filter parameters can be found to be electronically tunable [40]- [44] and can be controlled independently through various resistors: ω o by R 3 while the 3shows that the input admittance of the circuit is given by ( )…”

Although a variety of applications of the OTRAs have been reported in literature, the pole of the transresistance gain Rm of the OTRA has been usually considered to affect the performance of the circuits due to being parasitic. In this paper, the pole of the OTRA has been used to evolve some simple OTRA-based active-R circuits for realizing a synthetic inductor, single resistance controlled oscillator and low-pass/band-pass filter. The workability of all the proposed circuits has been verified by SPICE simulations and all the new circuits have been found to work as predicted by theory. The exemplary propositions suggest that it is worthwhile to further investigate new circuit designs using OTRA-pole.

“…In the derivation of equation (4) Figure 4 shows the second proposed square-rooting in which the MOS transistors M 1 and M 2 are operating in triode region and are used to obtain the basic squarerooting function. The MOS transistors M 3 and M 4 are also operating in the triode region and are used to realize floating voltage controlled resistor [10]. After taking the model parameters of the CMOS process from [11], V g =2.63V, L 1 =L 2 , W 1 =0.2455W 2, a routine analysis of the proposed circuit then gives the following expression for its output voltage…”

One new squaring and two new square-rooting circuits based on CDBAs have been introduced. The new squarer circuit consists of a CDBA, two NMOS transistors and one resistor. On the other hand, the first squarerooting circuit consists of two CDBAs, two NMOS transistors while the second square-rooting circuit consists of only a single CDBA, two NMOS transistors and two PMOS transistors. The proposed circuits exhibit wide input voltage range, very small error and offer low output impedance to facilitate easy cascading without requiring additional buffers. PSPICE simulation results are included which confirm the practical workability of the new circuits.

“…It is a well known fact that an all-pass filter (phase shifter) topology like previously reported first-order signal processing units [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] finds wide , which is suitable for high frequency applications, contains three CMOS transistors, a floating resistor for biasing purpose and a large coupling capacitor for dc isolation of the load. The circuit reported in 12 is a square-rootdomain CM filter which needs two identical bias currents.…”

In this paper, a new current-mode (CM) circuit for realizing all of the first-order filter responses is suggested. The proposed configuration contains low number of components, only two NMOS transistors both operating in saturation region, two capacitors and two resistors. Major advantages of the presented circuit are low voltage, low noise and high linearity. The proposed filter circuit can simultaneously provide both inverting and non-inverting first-order low-pass, high-pass and all-pass filter responses. Computer simulation results achieved through SPICE tool and experimental results are given as examples to demonstrate performance and effectiveness of the proposed topology.
