Abstract

A traditional pulse generation circuit based on the pulse-forming-line (PFL) is implemented in a commercial 0.13 μm digital CMOS technology. A meandered on-chip coplanar waveguide is used as the PFL, and CMOS transistor is used as switch in the Cadence Spectre simulation. The circuit sample is fabricated and tested. Pulses of ∼170 ps durations and 120-200 mV amplitudes are obtained when the power supply is tuned from 1.2 V to 2 V. The results show that the traditional PFL based circuit can be implemented in standard CMOS technology for on-chip short pulse generation. Furthermore, the PFL circuits significantly extend the short pulse generation capabilities of CMOS technology.

摘要

一种基于脉冲形成线（PFL）的传统脉冲产生电路采用商用0.13μm数字CMOS技术实现。在Cadence Spectre仿真中，采用曲折型片上共面波导作为脉冲形成线，并使用CMOS晶体管作为开关。对该电路样本进行了制作和测试。当电源电压从1.2V调至2V时，可获得持续时间约为170ps、幅度为120 - 200mV的脉冲。结果表明，基于传统脉冲形成线的电路可在标准CMOS技术中实现片上短脉冲产生。此外，脉冲形成线电路显著扩展了CMOS技术的短脉冲产生能力。
