Abstract: This work presents a single-current-controlled (SCC) sinusoidal oscillator that
explicitly generates both current and voltage outputs, and employing only a single
current-controlled conveyor transconductance amplifier (CCCTA) as the active
building block, and three passive components. The presented circuit provides the
advantage features of independent electronic control of oscillation condition and
oscillation frequency, and use of all grounded passive components. The circuit also
exhibits low active and passive sensitivities and permits good frequency stability.
Computer simulation results obtained from PSPICE program using 0.35-μm BiCMOS
real process parameters are performed to confirm the excellent performance of the
proposed oscillator circuit.
