LOW VOLTAGE CURRENT CONVEYOR-BASED FIELD PROGRAMMABLE ANALOG ARRAY
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 1V supply. The FPAA is realized using IBM 90 nm CMOS technology model from MOSIS under voltage supply of +/- 0.5 V.
