Tunable active-R oscillator using a CFA

[摘要] References(16)Cited-By(4)A novel tunable sinusoid oscillator design using a negative polarity current feedback amplifier (CFA) and only three resistors, is presented. The design utilises the transimpedance pole of the CFA device (AD-844). Independent fo-tunability (3MHz to 40MHz) had been verified with both PSPICE macromodel simulation and hardware circuit implementation. The genreration is practically active insensitive.
