| Abstract: | The precise,low temprature shift constant current source is designed to transfer resistance signal to (voltage) signal for measuring temprature with platinum resistor in a biologic chip response instrument.Subtraction circuit is adopted in the signal processing circuit and A/D TLC1543 is used to gather three channels' signals.The circuit's construction is simple. It has high measurement, control accuracy and reliability. |
