Abstract :
In this paper a method of systematically generating sinusoidal oscillators with noninteracting controls using multiple current output operational transconductance amplifiers (MO-OTAs) is introduced. This is an exhaustive method through which all the desired circuits belonging to the investigated class can be generated. The frequency of oscillation (FO) and condition of oscillation (CO) of the oscillators derived using this method is realized electronically with the two transconductance parameters of the MO-OTA. Five novel canonic oscillators with both capacitors grounded are obtained, which can also realize second order bandpass (BP) transfer functions without changing the topologies. The natural frequency ω0 and the bandwidth ω0 /Q of three of the BP filters can be tuned independently by the two transconductance parameters
