Operating Temperature Range

Data acquisition and signal processing at elevated temperatures are facing various problems due to a wide temperature range operation, affecting the accuracy of the circuits' references and elementary building blocks. As the most commonly used analog building block, the operational amplifier (op-amp) with its various limitations has to be enhanced for wide temperature range operation. Thereby major effort is put into maximizing signal gain and simultaneously reaching high gain-bandwidth also for high temperatures. Future robust design approaches have to consider a growing operating temperature range and increasing device parameter mismatch due to the downsizing of integrated circuits. Addressing one of the major problems in circuit design for the next decades, compensating these effects through new design approaches will have a lasting impact on circuit design. In this paper we present a high gain operational amplifier with a folded-cascode and gain-boosted input stage, fabricated in a 1.0 μm SOI CMOS process. The operational amplifier was designed for an operating temperature range of −40…300°C. Major effort was put into a robust design approach with reduced sensitivity to temperature variations, targeting high precision applications in a high temperature environment. With a supply voltage of 5 V, the maximum simulated current consumption of the op-amp is 210 μA which leads to overall maximum power consumption of 1.05 mW. The open loop DC gain of the amplifier is expected to reach a minimum of 108 dB and a unity-gain-frequency of 1.02 MHz at a temperature of 300°C. For all temperatures the phase margin varies from 55…70 degrees for a 3 pF load.

The nozzle array structure fluidic gyroscope’s zero temperature compensation was researched. The fluidic gyroscope’s temperature characteristic was analyzed in the sensitive element and two zero temperature compensation methods were compared. Then, the software compensation method was used, which based on the Single chip microcomputer technology and realized temperature compensation for the gyroscope output signal. The results show that after the compensation, the gyroscope’s zero drift decreases from ≤1.3mV/°C to ≤0.1mV/°C and operating temperature range increases from normal temperature to -40°C~+60°C. Therefore, the fluidic gyroscope has the advantage of low zero drift and width operating temperature range after the zero temperature compensation, which provides the convenience for the production and application.
