چکیده
This paper presents a compact low-power bidirectional current mirror suitable for low-voltage applications. The key element is the use of a CMOS complementary input stage working in subthreshold regime; which allows setting a reduced bias current through the mirror. The circuit was simulated using LTSpice and presents class AB operation with a THD of 1% at 1MHz. The power consumption is close to 3μW as shown by simulations and experimental data from a fabricated prototype using 0.5μm CMOS technology.
