Voltage controllable oscillator based on current amplifiers and voltage buffer

Controllable oscillator based on adjustable current active elements and voltage buffer is presented in the paper. Signal flow graph method employing lossless and lossy integrator synthesis and nonstandard approach for adjusting of oscillation condition based on controllable current feedback are used. The work is focused on analysis of parasitic influences affecting real behavior of the circuit. Expected results and results obtained from real circuit measurement are compared.
