Koksal Received: 25 May 2007 / Revised: 3 March 2008 / Published online: 10 September 2008 © Birkhäuser Boston 2008 Abstract A new floating immittance function simulator circuit is proposed using two different active elements, a dual-output second generation current conveyor (DO- CCII) and an operational transconductance amplifier (OTA). The presented circuit can realize a positive and negative floating inductor, capacitor and resistor depending on the passive component selection. Since the passive elements are all grounded, this circuit is suitable for fully integrated circuit design. The circuit does not require any component matching conditions, and it has a good sensitivity performance with respect to tracking errors. Moreover, the proposed positive and negative inductance, capacitor and resistor simulator can be tuned electronically by changing the biasing current of the OTA or can be controlled through the grounded resistor or capacitor. The proposed floating inductor simulator circuit is demonstrated by using a SPICE simulation for 0.35 μm TSMC CMOS technology. The proposed circuit consumes an average power of 1 mW using ±1.5 V supply voltages. Keywords Floating immittance function simulator · Floating inductor simulator · DO-CCII · OTA M.
