Abstract

This brief presents a continuously regulated current mirror topology capable of providing a wide range of currents with high-precision and speed control features. The circuit combines a non-linear current-mode feedback solution for fast and energy-efficient operation with an input-referred regulated-cascode configuration for precise current mirroring. The proposed implementation has an output current ranging from 100 μA to 2 mA, exhibits a fast response time of ≈100 ns for the full range steps, while ensuring a high power efficiency (>90%) and low current copy errors (<0.5%).
