Bandgap Voltage Reference Low TC (13ppm/ °C), PSRR-42 dB @ 100kHz

Overview

This macro-cell bandgap voltage reference generator core designed for SilTerra 0.18µm CL18GH5 CMOS technology.

The core is ideal as a general purpose reference voltage in applications where low TC is required with quick response dynamic.

The circuit generates an unbuffered 1.23V, temperature compensated bandgap voltage reference (13ppm/◦C).

Internal start-up circuit allows that the reference voltage is available as soon as the power supply ramps up, so that no enable/disable function is necessary to start-up the circuit.

The core is easily re-targeted to any other CMOS technology
