Zusammenfassung:In this paper, a new CMOS minus-type current-controlled third-generation voltage conveyor (CC-VCIII-) is presented. As application example using the presented new active building block a novel voltage-mode first-order all-pass filter is proposed, where instead of floating resistor the electronically controllable intrinsic resistance of the Y terminal is used. Hence, the circuit is resistorless and it shows low sensitivity performance. The behavior of the all-pass filter is verified by SPICE simulations and the TSMC 0.35 μm level 3 CMOS process parameters are used to confirm the theoretical analysis.
