Abstract
In this paper we describe the characterisation of a full custom analogue current drive chip fabricated using the Alcatel Mietec 2.4 mu m CMOS process. The chip has been designed to drive currents in the micro-amp range through an array of six resistive polymer micro-bridge devices. It exhibits good d.c. stability, and a linear temperature coefficient of about -1.2x10(-3)/degrees C. The chip can be drive in an ac. as well as in a d.c. and gives a stable pulsed current source at frequencies of up to 10 kHz.
