“…Their popularity is mainly attributed to their independent tuning law for the Condition of Oscillation (CO) and the Frequency of Oscillation (FO). In the last decade, the SRCOs, using electronically controllable active devices like the Di erential Voltage Current Conveyor Transconductance Ampli er (DVCCTA) [1], the Di erential Voltage Current-Controlled Conveyor Transconductance Ampli er (DVCCCTA) [2], Current Controlled Current Di erencing Transconductance Ampli ers (CCCDTAs) [3,4], have been proposed. However, these active devices are not commercially available.…”

Abstract. This paper reports a new realization of linear Voltage-Controlled Oscillator (VCO) using three Current-Feedback Op-Amps (CFOAs), three analog multipliers, and only four passive components. Thus, minimum numbers of passive components are used to devise a canonic sinusoidal oscillator. The circuit provides non-interactive electronic tuning of both the Condition of Oscillation (CO) and the Frequency of Oscillation (FO) via the gains of two di erent analog multipliers. The impedance at output node exhibits low impedance which is easy to directly connect to load without any additional voltage bu er. The proposed circuit has been simulated in SPICE using macro-model of AD844 CFOA ICs and AD633 multiplier ICs.

“…In this respect, resistorless and electronically controlled realizations of sinusoidal oscillators are the attention for many researchers [6,7,8,9,10,11,12]. These oscillators do not external resistors, provide electronically tunability to the circuit parameters and are beneficial for compensating the process tolerances.…”

“…The circuit, however, both voltage and current quadrature outputs cannot be simultaneously realized and one of the capacitors cannot be grounded. In 2011, Jaikla et al introduced the differential voltage current controlled conveyor transconductance amplifier (DVCCCTA) device [12]. This device is comprised of a differential amplifier (DA) circuit, a current controlled second generation current conveyor (CCCII) circuit and an operational transconductance amplifier (OTA) circuit.…”

“…Resistorless and electronically controlled realizations of quadrature oscillators are becoming popular. Such circuits do not require external resistors, provide electronically tunability to the circuit parameters and are also beneficial for compensating the process tolerances [12]. Since in this paper we focus on resistorless and electronically controlled realizations of dual-mode quadrature oscillator design, we choose only single CCCCTA and two grounded capacitors.…”

Resistorless dual-mode electronically tunable quadrature oscillator using a single current controlled current conveyor transconductance amplifier (CCCCTA) and two grounded capacitors is presented. The proposed circuit can provide both voltage-mode and current-mode simultaneously. The circuit with grounded capacitors enjoys resistorless, electronically tunable, non-interactive frequency and condition control, generates two quadrature current outputs at high impedance nodes and two quadrature voltage outputs. H-Simulation program with integrated circuit emphasis (H-Spice) simulations using Taiwan Semiconductor Manufacturing Company (TSMC) 0.18 µm complementary metal oxide semiconductor (CMOS) technology process parameters are given to validate theoretical predictions.
