The influence of the peaking capacitor and the pressure of mixture gas on the performance of UV preionized pulsed HF laser is investigated.

35μm CMOS technology,three types of pre-equalized optoelectronic integrated receivers are designed by parallel resonant loop peaking technique,third-order ladder network peaking technique,and high-pass filter peaking technique,respectively,where a fingered dual-photodiode is applied wi.

In order to achieve a broad bandwidth,a capacitive peaking technique was adopted in the common-base topology and cascode amplifier in common-emitter topology.

Active inductor shunt peaking technology and noise optimization are used in the design of a trans-impedance amplifier,which overcomes the problem of inadequate bandwidth caused by the large parasitical capacitor of the CMOS photodiode.
