【 摘 要 】

References(20)Cited-By(7)The electronically tunable oscillator with a single-output and a multiple-output transconductor and with three passive grounded elements is presented and verified in this paper. The active elements are modeled on the transistor level for the possibility to implement the whole oscillator on chip. The characteristic equation and condition for oscillation are discussed together with the major influence of the parasitic properties of the active devices. Using the proposed concept an experimental verification employing two commercially available transconductance amplifiers is given via associated time-domain and frequency-domain results.
