“…A good example is logdomain integrated continuous-time filters (CTFs) that exhibit a very wide tuning range [6]. The other solution for extending the operating frequency range in analog integrated circuits is using some switchable or programmable components and building blocks [7]- [10]. The main issues associated with this approach are increasing the power consumption and Si area as well as the circuit complexity.…”

Abstract-A very wide tuning range MOSFET-C filter has been introduced. The wide tuning range in this filter has been achieved without using any switchable components or programmable building blocks, while, the cutoff frequency of the filter can be adjusted simply through a controlling bias current. The filter has a low-pass characteristics with fc = 20Hz to 184kHz while exhibiting a constant power consumption per cutoff frequency over its entire tuning range. The proposed MOSFET-C filter uses PMOS transistors in subthreshold regime for implementing floating and widely adjustable resistors. The ultra high resistivity of the resistances make them very suitable for implementing very low frequency and compact filters. Implemented in 0.18µm CMOS technology, the filter exhibits a relatively constant noise and linearity performance over its entire tuning range. The active area of the proposed MOSFET-C filter is 0.09mm 2 .

“…Continuoustime devices can be implemented by means of translinear elements [1,2], transconductors [3], current integrators [4] or current conveyors [5], while discrete-time implementations may use switched capacitor topologies [6,7] or switched current circuits. The FPAAs can be configured for applications such as filtering [8], neural networks [9], industrial control [10], signal processing [11], V-F converters and aerospace communications [12], among others.…”

Abstract-In this paper, the implementation of signal processing circuits on a novel translinear Field-Programmable Analog Array (FPAA) testchip is reported. The FPAA testchip is based on a 0.35-micron, fully CMOS translinear element, which is the core block of a reconfigurable analog cell. The FPAA embeds a 5 × × × 5 cell array. As implementation examples, a four-quadrant multiplier with five decade dynamic range and a programmable fourth-order low-pass filter with up to 7 M Hz bandwidth have been mapped on the translinear FPAA. 14 cells have been used for the four-quadrant multiplier while 18 cells were needed for the fourth-order low-pass filter.

“…They can be divided into continuous time, discrete time and mixed analog reconfigurable circuits. The continuous time class of reconfigurable circuits contains devices based on Operational Transconductance Amplifiers (OTA) [1]- [3], current conveyors [4], [5] and also a wide class of so called Externally Linear (ELIN) circuits -e.g. log domain [6], [7], square root domain and others.…”

Abstract-The aim of this paper is to present an overview of a new branch of analog electronics represented by analog reconfigurable circuits. The reconfiguration of analog circuits has been known and used since the beginnings of electronics, but the universal reconfigurable circuits called Field Programmable Analog Arrays (FPAA) have been developed over the last two decades. This paper presents the classification of analog circuit reconfiguration, examples of FPAA solutions obtained as academic projects and commercially available ones, as well as some application examples of the dynamic reconfiguration of FPAA.
