CM1012bg – 17.5nA Current Bias Ultra Low Voltage (1V), Ultra Low Power (90nW)

Power Management

This macro-cell is an ultra low power general purpose current bias generator core designed for LFoundry 0.15μm LF150 CMOS technology STD (Standard) and LP (Low Power) process.

The circuit generates 5 PMOS 17.5nA current branches and 1 PMOS 175nA branch for test purposes. The core can be adjusted or trimmed through a 3-bit digital bus. The current bias is temperature compensated. The circuit starts as soon as the power supply ramps up. Start-up circuit consumes no power in normal operation.

The core is easily retargeted to any other CMOS technology due to high portability MOSFET-only current bias architecture.
