Abstract

In this paper we present a low voltage symmetric and bidirectional current mirror based on clocked semi-floating-gate (CSFG) transistors used in low-voltage digital CMOS circuits. By imposing offsets to semi-floating-gate nodes the current level may be increased while maintaining a very low supply voltage. The offset voltages are used to shift the effective threshold voltage of the evaluating transistors. The proposed current mirror can operate at supply voltages below 200 mV. The simulated data presented are obtained using the Spectre simulator provided by Cadence and valid for a 90 nm CMOS process.
