Bandgap Voltage Reference - Low Integrated Noise (57.2µVrms) TSMC 40nm

This macro-cell is a low power voltage reference generator core designed for TSMC 40nm CRN40LP CMOS technology. The core is ideal as a general purpose reference voltage in applications where low output noise and wide PSRR band are critical. The circuit generates an unbuffered 570mV, temperature compensated bandgap voltage reference (57ppm/ C). Internal start-up circuit allows the reference is available as soon as the power supply ramps up, so none enable/disable function is necessary to start it up. It has three trimming bits for the coeficient temperature. It has a general purpose 3.2µA PTAT output current. The core is easily re-targeted to any other CMOS technology.
