Three oscillator families using the current feedback op-amp

Three alternative voltage-mode oscillator families using the current feedba ck op-amp are given. Each family includes three different oscillator circui ts, each of them employs a second order RC circuit, two resistors and a sin gle current feedback op-amp (CFOA). Two families employ voltage feedback an d the third family employs current feedback. The third family is generated from the recently reported unity gain inverting current mode all-pass filte rs. This family is suitable for realizing current-mode oscillators using a two-output current conveyor instead of the CFOA. PSpice simulation results for the current-mode oscillators are given.
