This paper presents a new realization of resistorless mixed-mode (i.e. both voltage-mode and currentmode) quadrature sinusoidal oscillator using a new active building block (ABB) called the differential voltage current-controlled conveyor transconductance amplifier (DVCCCTA). The proposed oscillator circuit uses a single DVCCCTA, two grounded capacitors (GCs) and does not employ any external li...

In this paper, a resistorless realization of high order voltage mode wave active filter based on differential voltage current controlled conveyor transconductance amplifier (DVCCCTA) is presented. The wave method is used for simulating reflected and incident wave for basic building block i.e. series inductor and configuring it for other passive element realization by making appropriate connecti...

A novel square wave generator (relaxation oscillator) with controllable frequency is described. It employs two universal current conveyors (UCC) and grounded passive elements. The generator includes integrator with two integration capacitors that alternate in charging which results in linear and precise control of frequency by voltage. New implementation of UCC with attractive properties in CMO...

This paper presents an alternative configuration for realizing a canonical voltage-mode first-order allpass (AP) section with electronic tuning. The proposed circuit is composed of only one CCCTA and one floating capacitor, which results in a simple and resistorless structure. Its phase response can be adjusted electronically through the external dc bias currents of the CCCTA. Simulation result...

In the present paper, very simple voltage-mode instrumentation amplifier (IA) and integrator structures including only grounded passive components yielding easy integration are proposed. The proposed IA and integrator use single differential difference current conveyor. The proposed IA without requiring critical passive component matching conditions can be constructed with only two small-valued...

A novel current conveyor, which can be used for realization of current conveyors of different forms, is presented. The proposed current conveyors are capable of operating at supply of & 1.0 V with rail-to-rail input and output voltage swings. The proposed structure operates as linear circuit element and has a bandwidth of 60 MHz for 1.2 pm CMOS technology. The circuit has many applications and ...

This work shows the experimental implementation of a chaotic communication system based on two Chua’s oscillators which are synchronized by Hamiltonian forms and observer approach. The chaotic communication scheme is realized by using the commercially available positive-type second generation current conveyor (CCII+), which is included into the AD844 device. As a result, experimental measuremen...

This paper presents an electronically tunable current-mode SIMO/MISO universal biquad filter using multi-output current controlled current conveyor transconductance amplifiers (MO-CCCCTAs). The proposed filter employs only two CCCCTAs and two grounded capacitors. The proposed configuration can be used as either single input multi-output (SIMO) or multi (three) input single output (MISO) current...

This paper is a tutorial introduction to field-programmable analog arrays, as well as a review of existing field-programmable analog array architectures, of both educational and industrial origin. Circuit issues relevant to the development of high-bandwidth FPAAs are presented. A current conveyor-based architecture, which promises to achieve video bandwidths, is described. Test results are pres...
