Voltage-mode Field Programmable Analog Array using Second Generation Current Conveyor

This paper is a tutorial introduction to field-programmable analog arrays, as well as a review of existing field-programmable analog array architectures, of both educational and industrial origin. Circuit issues relevant to the development of high-bandwidth FPAAs are presented. A current conveyor-based architecture, which promises to achieve video bandwidths, is described. Test results are presented for the CMOS current conveyor-based FPAA building block, with programmable transconductors and capacitors. Measurements indicate bandwidths in excess of 10 MHz, and functionality of amplifiers, integrators, differentiators, and adders. The die area is 1.5 mm× 3.5 mm in a 0.8 μm CMOS technology.

In this paper a low voltage low power field programmable analog array (FPAA) is realized. The FPAA configurable analog block (CAB) design is based on three-bit digitally controlled fully differential current conveyor. The FPAA consists of seven CABs. The CABs are directly connected together without adding extra hardware by placing them in a hexagonal lattice arrangement. A variable gain amplifier, tunable second-order low-pass filter, and a tunable second-order band-pass filter are realized as an application for the FPAA. The FPAA total power consumption is 105.12 mW at 1 V supply. The FPAA is realized using IBM 90 nm CMOS technology model from MOSIS under voltage supply of ±0.5 V.

Abstract A rapid prototyping method for designing mixed signal systems has been presented in the paper. The method is based on implementation of the field programmable analog array (FPAA) to configure and reconfigure mixed signal systems. A serial algorithmic analog digital converter has been used as an example. Three converter architectures have been selected and implemented FPAA device. To verify and illustrate converters operation and prototyping capabilities, implemented converters have been excited by a sinusoidal signal. Analog sinusoidal excitations, digital responses and sinusoidal waveforms after reconstruction are presented.
