Abstract

A quite simple adjustable oscillator based on adjustable selective section and lossless integrator is presented in this paper. First order selective section is based on current mode adjustable attenuators employing current-mode multipliers. Characteristic equation, features of electronic adjusting, sensitivities, distortion of output signal and influences of parasitic elements are discussed. Theoretical and estimated assumptions are supported by simulation and experimental results.
