A kind of temperature collection circuit architecture applicable to medical instruments is described in detail in the article. The characteristics and working principle are analyzed. The circuit structure is composed by a temperature sensor, constant current source, low-pass filter circuit and ADC pre-processing circuit. The signal was firstly First transmitted to the ADC, then the signal is transmitted to the temperature control MCU which judges the temperature after converted. Analysis and calculation show that the circuit is safe and reliable. The indexes including bandwidth, noise, resolution and accuracy meet the design requirements, which ensures the reliability of the system.
