This paper introduces several novel active RC oscillator circuits using the operational transresistance amplifier (OTRA) as the basic active building block. A general configuration using a single OTRA is introduced, from which a minimum component oscillator is generated. Four new oscillator circuits based on using two OTRAs are reported. HSpice simulations to confirm the analysis are given.
