(English Abstract) |
In this paper, we propose an improved ground bounce-free output buffer. In order to reduce the ground bounce voltage, we suggest a new architecture of the ground bounce-free output buffer. It is to control the cut off and saturation mode of two N-MOS transistors in an output buffer with a time difference. The simulation results show the -0.7V ground bounce voltage at any condition. A fabricated sample using 0.6%u339B CMOS DLM process demonstrates the ground bounce noise level less than -0.7V at 0%u2103 degree. These results show the lower ground bounce noise than the conventional output buffer at the same output low voltage level(VOL). And also the average high-to-low propagation delay of 3.5ns is achieved. This figure is comparable to 3.6ns of the conventional output buffer. |
