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

A voltage mode Field Programmable Analog Array (FPAA) is presented in this paper. The FPAA is an array consisting of 30 Digitally Programmable Second Generation Current Conveyors (DPCCII-). The FPAA is made from seven configurable analog blocks (CABs) formed with DPCCII-. The CABs are directly connected to each other through direct wiring. This direct wiring methodology is realized because the DPCCII- outputs can be set to zero using a three-bit digital codeword. The FPAA is realized using 90nm CMOS technology model. The standby DC power consumption of the FPAA is 72.3mW from balanced supply voltage +/- 0.5V. A tunable second order universal filter is realized using the proposed FPAA. The filter's cutoff frequency is tuned from 5.8MHz to 11.6MHz.
