Low Voltage Programmable Double-Gate MOSFETs Current Mirror and Its Application As Programmable-Gain Current Amplifier

Abstract

This paper presents programmable simple and cascode current mirrors, based on novel double gate (DG) MOSFETs. The programmable current mirror has a wide tuning range, a wide bandwidth and low supply voltage of 1V. As an application of the programmable current mirror, we present a programmable-gain current amplifier. SPICE simulation results for 100-nm DGMOSFET and 1V supply voltage indicate good performance for the proposed circuits.Index Terms-DGMOSFET Circuits, Low Power low voltage Circuits, programmable Current Mirrors, Nano-Technology.

Tunable current mirror and its application in LNA

“…The tunable CMs are required widely in applications such as current-mode amplifying [1] and filtering [2] . Also, some related techniques have been reported in the past few years.…”

“…Another accurate wide swing CM using the npn-NMOS cascade instead of the NMOS-NMOS cascade was presented by Yang in 2008 [4] . A programmable CM composed of DGMOSFET has been introduced by Hamed in 2007 [1] . Guvenc has proposed a tunable linear CM composed with both BJT and MOSFET in 2008 [5] .…”
