Switched-Resistor Filters-A Continuous Time Approach to Monolithic MOS Filter Design

Absfruct-A method of designing continuous-time active RC filters which employ only capacitors and FET transistors is presentedl. The effective RC time constants of these filters are determined by capacitor ratios. The filters employ switched resistors. These filters can uric any existing active RC or passive RC topology as the basis for the design and inherit the sensitivity properties of the c...

PSpice for Filters and Transmission Lines

In this book, PSpice for Filters and Transmission Lines, we examine a range of active and passive filters where each design is simulated using the latest Cadence Orcad V10.5 PSpice capture software. These filters cannot match the very high order digital signal processing (DSP) filters considered in PSpice for Digital Signal Processing, but nevertheless these filters have many uses. The active f...

A Programmable ASIC Design of a Low Sensitivity Sampled Data Filter

In this paper, a CMOS custom Integrated Circuit featuring a multi-stage Universal Switched-Capacitor (SC) Filter is introduced. The network is based on the Generalized Immittance Converter (GIC) configuration, known for its excellent passive and active sensitivities. CMOS switches were used for elements relocation and are digitally controlled to select and realize different filter topologies. S...

Design of a Low-Distortion 22-kHz Fifth-Order Bessel Filter

Abs&act-A linearity improvement technique employing passive resistors and current-steering MOS transistors as a variable resistance element is proposed to implement a low-distortion filter in CMOS technology. This proposed implementation relies on the linearity of the passive resistors and the tunability of the current-steering MOS transistors operating in the triode region to overcome the limi...
