The circuit, which was developed for use with large-area heat-flow sensors that employ resistance temperature detection, uses a synchronous rectifier driven by a square wave. It is shown that the circuit has good linearity, resolution, and immunity to external and internal noise.&lt;/p&gt;</style></abstract><call-num><style face="normal" font="default" size="100%">LBL-18002</style></call-num><custom1><style face="normal" font="default" size="100%">&lt;p&gt;Windows and Daylighting Group&lt;/p&gt;</style></custom1><custom2><style face="normal" font="default" size="100%">LBL-18002</style></custom2></record></records></xml>
