The picture 1 shows a amplifier circuit formed by 2SJ114.It can amplify square wave signal of ±l0V to ±48V. This circuit adopts P channel and N channel power MOSFET(VT7 and VT8) to form switch circuit. And the switch circuit is symmetry in the face and the below sides, so it can output dual polarity voltage. Due to the operating mode of VT7 and VT8 (the same power source), it needs to use VT3 to VT6 transistors to form the low resistance drive circuit in order to improve the response speed of gates.
