Embodiment Construction
[0017] Such as figure 2 Shown is a modulation drive output stage circuit of a preferred embodiment of the present invention, which is a symmetrical circuit on the left and right sides. The modulation drive output stage circuit includes a switch control circuit section 22 and a current generation circuit section 21 . The switch control circuit section 22 receives a differential input voltage (V IP , V IN ), where the differential input voltage comprises the first differential voltage V IP and the second differential voltage V IN . The current generation circuit part 21 is connected to the switch control circuit part 22, and outputs a differential output current (I OP , I ON ), where the differential input voltage includes the first differential current I OP and the second differential current I ON .
[0018] In an embodiment of the present invention, the current generating circuit part 21 includes a first transistor M 1 , the second transistor M 2 , the seventh tran...
