A square-wave generator using ECCII

This paper presents a new square-wave generator using electronically tunable second-generation current conveyors (ECCII). The proposed circuit employs one ECCII, two resistors and one resistor. Unlike previous works, oscillating condition can be given by current gain of ECCII and the output frequency can be controlled by changing resistor. Both voltage and current signals can be obtained into a single topology. The proposed circuit is simulated using PSPICE simulators to confirm the workability of the circuit.
