摘要：

A simple design for a high-performance DC resistance thermometer bridge is presented. The bridge takes advantage of low-drift, low-offset operational amplifiers to obtain the low noise levels and flexibility previously available only from AC bridges. The characteristics of the bridge's performance are discussed and spectral measurements with the circuit are considered.
