Low-Power Bandgap Reference - Low Integrated Noise (62.5µVrms) in 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 547mV, temperature compensated bandgap voltage reference (62.5ppm/ 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 800nA PTAT output current. The core is easily re-targeted to any other CMOS technology.
