“…2 is used for simulation. The transistors are modeled by the TSMC 0.25µm CMOS technology parameters [14]. As an example design, the active and passive components were chosen as C 1 =C 2 = 100 pF, I A1 =I A2 = 30 μA (R p1 =R p2 = 2.586 kΩ), I B1 =I B3 = 104 μA, I B2 =I B4 =100 μA, respectively.…”

This paper presents a new electronically tunable mixed-mode quadrature sinusoidal oscillator using new allpass section as an building block. The oscillator is consisted of two allpass sections. Each allpass section employs one currentcontrolled current differencing transconductance amplifier and one grounded capacitor. The condition of oscillation and the frequency of oscillation can be controlled independently and electronically by adjusting the bias currents. The oscillator also offers two explicit quadrature voltage and quadrature current outputs into a single topology. The workability of the proposed structure is verified by PSPICE simulators based on 0.25 µm TSMC CMOS process.

“…These circuits utilize the intrinsic resistances of active components for independent controlling the CO and FO. However, the internal structures of used active components in [15], [16] complicate with the use of more transistors. This paper presents a new mixed-mode quadrature oscillator using a single DDCCTA along with four grounded components, which is easy for monolithic integration [17].…”

“…Although the CO and FO of the circuit are independently tunable, it suffers from the use of two active components. The mixedmode QOs based on a single active component have been proposed [15], [16]. These circuits utilize the intrinsic resistances of active components for independent controlling the CO and FO.…”

“…Such type of QO is the so-called mixed-mode QO circuit. Several realization of mixed-mode QOs based on various active components like differential voltage current conveyor (DVCC) [9], [10], current conveyor (CCII) [11], zcopy current follower transconductance amplifier (ZC-CFTA) [12], current differencing transconductance amplifier (CDTA) [13], current controlled CDTA [14], [15] and differential voltage current-controlled conveyor transconductance amplifier (DVCCCTA) [16] have been received considerable attention. However, the circuits reported in [9]- [13] contain a lot of active and passive components, so these circuits require a large area for fabrication.…”

A new mixed-mode quadrature oscillator using a single differential difference current conveyor transconductance amplifier (DDCCTA), two grounded resistors, and two grounded capacitors is presented. The proposed circuit provides both quadrature voltage and quadrature current outputs simultaneously. The condition of oscillation (CO) and frequency of oscillation (FO) of the circuit are orthogonally controllable. The circuit is beneficial to monolithic integrated circuit implementation by using all grounded passive components. Moreover, the active and passive sensitivities of the proposed configuration are low. The validity of the proposed oscillator has been established by PSPICE simulations using MIETEC 0.5 μm CMOS technology.
