用tran仿真时,outputs-to be saved,选原理图上的节点terminal,自然可以仿真出电流,但电流有正有负,方向应该是从哪头流到哪头呢? MOS管的话,Drain极应该是正确的电流流向,Source极电流就完全是相反的。也就是说,在drain极测,电流流向为drain to source, 在source极测,电流流向是source to drain,实际是dra ...
The basic strategy with non-sinusoidal waveforms is to start with an estimate of how many harmonics might be required, and set the oversample factor to 8. Run the simulation. Reduce the number of harmonics by about 50% and run the simulation again. If the answer does not change, reduce the number o ...
对于射频和微波在什么频段的定义,我一直信奉的是Pozar 在《microwave engineering》第四版中的描述: The field of radio frequency (RF) and microwave engineering generally covers the behavior of alternating current signals with frequencies in the range of 100 MHz (1 MHz = 10^6 Hz) to 1000 GHz (1 GHz = ...
