ACTIVE-C OSCILLATOR.

Operational transconductance amplifiers have three main advantages over standard operational amplifiers. They require few if any resistors, tuning of their transfer gain (g//m) is electronic and highly linear, and their high-frequency performance is more reliable. For these reasons, o. t. as are replacing op-amps in oscillator and active filter designs. Recently, a number of o. t. a. -based oscillators have been proposed. The device described has two grounded capacitors and is therefore highly suitable for integration. Moreover it has non-interactive electronic tuning and low sensitivity.
