Overview

This macro-cell is a low noise, high PSRR voltage reference core designed for TSMC 0.18um (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 25uA reference current source (PTAT) for external use is also included.

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

Key features

  • Reference Voltage: 1.185V ±1% (w/ trimming)
  • Low noise: 63nV/√Hz (10Hz to 25kHz)
  • High PSRR: –80dB (up to 100kHz)
  • Temperature compensated: < 40ppm/oC
  • Supply voltage: 5.0V ±10%
  • Buffered reference output: 100uA (max)
  • PTAT reference current output available
  • Area: 0.101mm2
