A 1-μW 600-ppm/◦C Current Reference Circuit Consisting of Subthreshold CMOS Circuits
A low-power CMOS current reference circuit was developed using a 0.35-μm standard CMOS process technology. The circuit consists of MOSFET circuits operating in the subthreshold region and uses no resistors. It compensates for the temperature effect on mobility μ and threshold voltage VTH of MOSFETs and generates a reference current that is insensitive to temperature and supply voltage. Theoreti...
متن کاملHigh-Resistance Resistor Consisting of a Subthreshold CMOS Differential Pair
We propose a CMOS circuit that can be used as an equivalent to resistors. This circuit uses a simple differential pair with diodeconnected MOSFETs and operates as a high-resistance resistor when driven in the subthreshold region of MOSFETs. Its resistance can be controlled in a range of 1–1000 MΩ by adjusting a tail current for the differential pair. The results of device fabrication with a 0.3...

متن کاملCurrent-input current-output CMOS logarithmic amplifier based on translinear Ohm’s law
State-of-the-art logarithmic amplifiers use a transimpedance technique based on the exponential dependence between input current and output voltage as exhibited by p-n junction diodes, bipolar transistors and MOS transistors in the subthreshold region. Presented is a CMOS current-input current-output logarithmic amplifier based on a translinear Ohm’s law principle which involves a floating volt...

This paper proposes a low voltage CMOS nano-ampere current reference circuit and presents its performance with circuit simulations in 180-nm technology. The proposed circuit consists of biasvoltage, current-source and offset-voltage sub-circuits with most of MOSFETs operating in subthreshold region. Simulation results show that the circuit generates a stable reference current of 110-nA in suppl...
