11.1 INTRODUCTION
Generation of sinusoidal oscillations of a given frequency is highly essential in any electronic circuit. Using the concept of positive feedback generates such sinusoidal oscillations. Active devices such as transistor, FET or Op-Amp (operational amplifier) are employed in the generation ...
