Using a general oscillator structure, new oscillator circuits are systematically derived. These oscillator circuits use two operational transconductance amplifiers (OTAs) and one externally connected passive element, exploiting the inherent zeros of the OTAs to advantage. The feasibility of obtaining oscillation using only two OTAs without externally connected passive elements is investigated. Experimental results are included.
