Embodiment Construction
[0014] The present invention will be further described below in conjunction with the accompanying drawings.
[0015] like figure 1 , 2 As shown, a micro-current / voltage conversion signal conditioning circuit includes an external detection signal input unit I, an inverter amplifier II, a first voltage follower III, a second voltage follower IV and an A / D conversion unit V, so The inverter amplifier II and the first voltage follower III are both connected to the external detection signal input unit I, and the inverter amplifier II and the first voltage follower III are both A / D converted through the second voltage follower IV The unit V is connected, and the external detection signal input unit I provides an external detection signal. The external detection signal is processed by the inverting amplifier II and the first voltage follower III and synthesized to the second voltage follower IV for processing, and then output after processing. To the A / D conversion unit V.
