Research note two novel voltage(current) controlled integrable oscillators
Two novel voltage(current) controlled oscillator circuits are presented. Each circuit uses a single operational amplifier, a single operational transconductance amplifier, and either a single resistor or a single capacitor. ...
Two new integrable active-C OTA-based linear voltage (current)-controlled oscillations
Two new integrable active-C oscillators using operational transconductance amplifiers (OTAs) are presented. In both circuits, the frequency of oscillation can be linearly controlled by adjusting the biasing voltage (current) ...
Research note: A new OTA-based active-C oscillator
A new resistorless active-C OTA-based oscillator is presented. The circuit uses four OTAs and two capacitors. The oscillation frequency can be electronically tuned without affecting the condition of oscillation. The circuit ...
