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

摘要

The authors have previously presented a state variable synthesis approach to derivation of current feedback op-amp (CFOA) based single-resistance-controlled oscillators (Senani and Gupta, 1997). An extension of the previous approach is presented to facilitate the derivation of a number of new SRCO circuits which require no more than two CFOAs.
