Original Abstract
In this paper, a new voltage-mode first-order all-pass filter suitable for low-voltage operation is presented. The circuit is composed of two n-channel metal-oxide semiconductor field effect transistors (NMOS)-based inverting voltage buffer (IVB), single capacitor, and three resistors. Replacing one of resistors by NMOS-based voltage-controlled resistor, the pole frequency of the filter can be controlled electronically. The theoretical results are verified by SPICE simulations using TSMC 0.13 um level-7 CMOS process parameters, where +-0.65 V supply voltages of the IVB is used.
Keywords
