A 10 fJ·K ²Wheatstone Bridge Temperature Sensor with a Tail-Resistor-Linearized OTA

This article describes a highly energy-efficient Wheatstone bridge temperature sensor. To maximize sensitivity, the bridge is made from resistors with positive (silicided diffusion) and negative (poly) temperature coefficients. The bridge is balanced by a resistive (poly) FIR-DAC, which is part of a 2nd-order continuous-time delta-sigma...

A 6.6-μW Wheatstone-Bridge Temperature Sensor for Biomedical Applications

This letter presents a compact, energy-efficient, and low-power Wheatstone-bridge temperature sensor for biomedical applications. To maximize sensitivity and reduce power dissipation, the sensor employs a high-resistance (600 kΩ ) bridge that consists of resistors with positive (silicided-poly) and negative ( n -poly) temperature coefficients...

A Resistor-Based Temperature Sensor With a 0.13 pJ·K² Resolution FoM

This paper describes a high-resolution energy-efficient CMOS temperature sensor, intended for the temperature compensation of MEMS/quartz frequency references. The sensor is based on silicided poly-silicon thermistors, which are embedded in a Wien-bridge RC filter. When driven at a fixed frequency, the filter exhibits a temperature-dependent...

A 0.25 mm²-Resistor-Based Temperature Sensor With an Inaccuracy of 0.12 °C (3σ) From -55 °C to 125 °C

This paper describes a compact, energy efficient, resistor-based temperature sensor that can operate over a wide temperature range (-55 °C-125 °C). The sensor is based on a Wheatstone bridge (WhB) made from silicided poly-silicon and non-silicided poly-silicon resistors. To achieve both area and energy efficiencies, the current output of the WhB...

Greenhouse transitionzone

The Airey building blocks in Amsterdam currently don’t meet regulations set for 2020 that state that buildings should operate in an energy neutral manner. The goal of this research is to establish whether addition of greenhouses can improve indoor thermal comfort and reduce total energy use in such a way that they contribute to energy neutrality...
