Analysis of BDMOS and DTMOS Current Mirrors in 130 nm CMOS Technology

Abstract

In this paper, an analysis of basic Current Mirror (CM) topologies was performed with a focus on comparison of conventional realization to Bulk-Driven (BD) and Dynamic-Threshold (DT) equivalents, in terms of main properties. These circuits were designed in 130 nm CMOS technology using the supply voltage of 0.6 V and laid out on a test-chip. Fabricated circuits were analyzed and their characteristics compared to the simulation results. The achieved results prove that these unconventional circuit design techniques are quite promising for contemporary ultra low-voltage analog Integrated Circuits (ICs)
