A time-delay technique to improve GBW on negative feedback amplifiers

Three new grounded capacitor current mode low-pass filters using two inverting second-generation current conveyor (ICCII) or one double output ICCII are given. The circuits employ the minimum number of passive circuit components, namely two resistors and two capacitors. The circuits are generated from three new voltage mode low-pass filters realized with the ICCII. A new grounded capacitor CCII+ current mode low-pass filter is generated from one of the new voltage mode low-pass filters employing two ICCII-. A new grounded passive component low-pass filter with independent control on Q and using three ICCII+ is also introduced. Spice simulation results based on using the 0.5 µm CMOS model are included to support the theoretical analysis. Copyright © 2007 John Wiley & Sons, Ltd.
