A new circuit configuration for the realisation of an electronically tunable sinusoidal oscillator
is presented. The proposed circuit uses only one current backward transconductance
amplifier (CBTA), two grounded capacitors and one resistor. Using current controlled CBTA
(CC-CBTA) instead of the CBTA, the resistor can be completely removed. It has also current-
mode (CM) and voltage-mode (VM) outputs, simultaneously. The workability of the proposed
structure has been demonstrated by both simulation and experimental results.

This paper presents a novel electronically tunable third‐order sinusoidal oscillator
synthesized from a simple topology, employing current‐mode blocks. The circuit is realized
using the active element: Current Controlled Conveyors (CCCIIs) and grounded passive
components. The new circuit enjoys the advantages of noninteractive electronically tunable
frequency of oscillation, use of grounded passive components, and the simultaneous
availability of three sinusoidal voltage outputs. Bias current generation scheme is given for …
