Abstract

MOLINAR-SOLIS, Jesús E. et al. A 3μW Low-Power CMOS Class-AB Bilateral Current Mirror for Low-Voltage Applications. Comp. y Sist. [online]. 2016, vol.20, n.4, pp.723-728. ISSN 1405-5546.  http://dx.doi.org/10.13053/cys-20-4-2489.

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.

Keywords : Analog integrated circuits; MOS integrated circuits.
