Embodiment Construction
[0029] In order to further illustrate the technical means adopted by the present invention and the achieved effects, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings and specific embodiments. Such as figure 1 The entire ultra-wideband pulse includes five parts: switch circuit, amplifier circuit, differential circuit, DC bias module, negative feedback network, and shaping network.
[0030] The differential circuit, switch circuit, amplifying circuit, and shaping network are connected in sequence, and the DC bias module provides DC bias for the switch circuit and the amplifying circuit.
[0031]The first differential circuit is composed of C1 and R1, which is connected to the external input crystal oscillator to extract the edge of the external crystal oscillator input signal; the negative feedback network is composed of C2 and R3, which greatly reduces the influence of the stability of ...
