Low-Noise Bandgap Reference - Low Noise: 63nV/√Hz, PSRR: -80dB TSMC 0.18μm CMOS (CLM18)

This macro-cell is a low noise, high PSRR voltage reference core designed for TSMC 0.18μm (CLM18) CMOS technology. The core is ideal for applications where noise performance is critical. The circuit generates a buffered 1.185V, temperature-compensated bandgap voltage reference (40ppm/◦C). A 5-bit trimming is available and guarantees ±1.5% output voltage accuracy. A 25μA reference current source (PTAT) for external use is also included.
