“…The CFA device [1,10,11] is equivalent circuit to second-generation current conveyor (CCII), which is followed by voltage buffer. Principle of electronic control of input (intrinsic) resistance (labeled as R X ) of current input terminal X is already well known [11,29], where only one CCII and bias control (I b ) is sufficient [4,29].…”

In this paper, a new electronically tunable quadrature oscillator (ETQO) based on two modified versions of current feedback amplifiers (CFAs), the so called double current controlled CFA (DCC-CFAs) is presented. The frequency of oscillation (FO) of the proposed voltage-mode (VM) ETQO is electronically adjustable by current gain or by varying the intrinsic resistance of the X terminal of the active element used. The condition of oscillation (CO) is adjustable by current gain independently with respect to frequency of oscillation. Simultaneous control of current gain and intrinsic resistance allows linear control of FO and provides extension of frequency tuning range. In the proposed circuit all the capacitors are grounded. The use of only grounded capacitors makes the proposed circuit ideal for integrated circuit implementation. The presented active element realized by using BiCMOS technology and the behavior of proposed circuit are discussed in details. The theoretical results are verified by SPICE simulations based on CMOS ON-Semi C5 0.5 µ m and bipolar ultra high frequency transistor arrays Intersil HFA 3096 process parameters.

“…The CDDITA is one of the recent active ABB which have been introduced in [30]. Figure 1 shows the symbolic representation of CDDITA, where P and N are input ports, z is auxiliary port, X+ and X− are output ports and V is buffered port with all ports at high impedance level except P and N which are low impedance ports.…”

This realization of a voltage-mode first order voltage-mode all pass filter (VM-APF) employing single current differencing differential input transconductance amplifier (CDDITA) as active component is presented. The proposed configuration employs one CDDITA along with two resistors and one grounded capacitor. The pole frequency and phase shift of proposed VM-APF are electronically tunable by transconductance of CDDITA. The proposed circuit is verified by SPICE simulations.

“…The analysis given below starts from the paper [11], which specifies the requirements for the characteristics of a memristive system which would be useful for its practical utilization in various areas of the analog signal processing. The bipolar memristive system with the voltage threshold (BMST) [12][13][14] is selected as a useful type for a signal rectification.…”
