| Abstract: | In the purpose of space camera application,by analyzing the relationship of infrared detector＇s output signals and bias voltages,high precision voltage references and amplifiers which have ultra low offset,drift and bias current are used in the bias voltage supply circuit to guarantee the precision of the bias voltages.Negative feedback or voltage-follower structure improves the stability of the circuit.By simulation and test in laboratory,the results show that the fluctuate of the bias voltages is smaller than 5mV and the RMS noise is smaller than 100μV.The circuit is reasonable and feasible. |
