Low-voltage CMOS voltage squarer
2009 16th IEEE International Conference on Electronics, Circuits and Systems - (ICECS 2009), 2009A voltage squarer based on bulk-driven PMOS transistors is proposed in this paper. Circuit topology employs a voltage attenuator and the quadratic I D /V G characteristic of a MOS in saturation. The squarer was designed with a 0.8V supply voltage using standard 0.35um CMOS process, which offers large value of threshold voltage.

A low-power low-voltage MOSFET-only voltage reference
2004 IEEE International Symposium on Circuits and Systems (IEEE Cat. No.04CH37512), 2004A low-power low-voltage MOSFET-only voltage reference featuring very good temperature stability and referred to the positive power supply is proposed. It compensates for the temperature dependence of a gate-to-source voltage of an MOS transistor working in the weak inversion region with a proportional-to-absolute-temperature voltage generated by a pair

A low-voltage low-power voltage reference based on subthreshold MOSFETs
IEEE Journal of Solid-State Circuits, 2003In this work, a new low-voltage low-power CMOS voltage reference independent of temperature is presented. It is based on subthreshold MOSFETs and on compensating a PTAT-based variable with the gate-source voltage of a subthreshold MOSFET. The circuit, designed with a standard 1.2-/spl mu/m CMOS technology, exhibits an average voltage of about 295 mV ...

Voltage references for ultra-low supply voltages
2008 IEEE Custom Integrated Circuits Conference, 2008The majority of integrated voltage references have, so far, been limited to a minimum supply voltage above 0.7-V often due to the voltage headroom required for the forward-biased operation of a PN-junction. This paper reviews design techniques for low voltage reference design and explores the feasibility of designing a voltage reference with a supply ...
