Voltage & Current References - Flexible Supply Voltage (1.6­3.6V), Low Power (5µA) XFAB 0.35 um

This macro-cell is a low consumption combo voltage and current reference core designed for X-FAB 0.35µm XH035 CMOS technology. The circuit generates an unbuffered 1.29V, temperature compensated voltage reference (70ppm/ C) and provides a 1.6µA PMOS current branch (200ppm/ C). It also provides a digital output signal to indicate that the reference voltage and current are at the correct levels (reference OK). The voltage reference can be trimmed against process variations by a 4-bit digital bus. The core is easily retargeted to any other CMOS technology with R-poly devices.
