Abstract EN
This study proposes three new sinusoidal oscillators based on an operational transresistance amplifier (OTRA).
Each of the proposed oscillator circuits consists of one OTRA combined with a few passive components.
The first circuit is an OTRA-based minimum RC oscillator.
The second circuit is capable of providing independent control on the condition of oscillation without affecting the oscillation frequency.
The third circuit exhibits independent control of oscillation frequency through a capacitor.
This study first introduces the OTRA and the related formulations of the proposed oscillator circuits, and then discusses the nonideal effects, sensitivity analyses, and frequency stability of the presented circuits.
The proposed oscillators exhibit low sensitivities and good frequency stability.
Because the presented circuits feature low impedance output, they can be connected directly to the next stage without cascading additional voltage buffers.
HSPICE simulations and experimental results confirm the feasibility of the new oscillator circuits.
