Abstract

ABSTRACT: A novel fully differential digitally programmable current conveyor (DPCCII) is presented in this paper. The programmability of the proposed DPCCII is achieved using three‐bit MOS R‐2R ladder current division network. The DPCCII is used to realize a field programmable analog array (FPAA). The FPAA consists of seven configurable analog blocks arranged in a hexagonal form. The FPAA power consumption is 72.3 mW from 1 V voltage supply. A second‐order programmable universal filter is realized using the proposed FPAA as an application. All the circuits are realized and simulated using 90 nm IBM CMOS technology model under balanced supply voltage of ±0.5 V. Copyright © 2012 John Wiley & Sons, Ltd.
