This paper proposes an active-RC filter that achieves a wide pseudo-continuous bandwidth-tuning range and a wide gain range with fine steps using a novel switched resistor architecture. A channel-selection filter with the proposed resistor bank is de

This paper proposes a technique for two-stage operational amplifiers (OPAMPs) to optimize power consumption according to various channel conditions of wireless communication systems. The proposed OPAMP has the ability of reducing the quiescent curren

For frequency division duplex (FDD) wide band code division multiple access (WCDMA) system, transmit (TX) signal leakage at the receiver input degrades the receiver performance. Previously, to cancel the TX leakage, a frequency selective feedback was

The matrix determinant computation system (MDCS) is developed in subthreshold current-mode for an analog signal processing. By utilizing the translinear loop principle and the novel differential architecture, the MDCS can perform accurate addition, s

A semi-active high-efficient (SA-HE) CMOS rectifier with reverse leakage control has been developed. It employs a cross-coupled NMOS pair and two leakage control comparators to reduce reverse charge leakage current. In addition, the adaptive body bia
