State variable synthesis of single resistance controlled groundedcapacitor oscillators using only two CFOAs

摘要

The authors have previously presented a state variable synthesisnapproach to derivation of current feedback op-amp (CFOA) basednsingle-resistance-controlled oscillators (Senani and Gupta, 1997). Annextension of the previous approach is presented to facilitate thenderivation of a number of new SRCO circuits which require no more thanntwo CFOAs
