#171780 - Device characterization |
I need to check if my VHF JFET's characteristics is up to the manufacturer's specs or not. I did Id vs Vgs plot, which was easy to do. However, I am not able to think of a circuit/formula that can help me plot the (a) Junction capacitance/transconductance vs Vgs, (b) output conductance vs. Id and (c) output admittance vs Id.
I hope you guys can suggest me some idea. |

| As I said you need AC and DC tests | 01/01/70 00:00 | |
| Not necessarily... | 01/01/70 00:00 | |
| Datasheet? | 01/01/70 00:00 | |
| None unfortunately | 01/01/70 00:00 | |
| What about other datasheets | 01/01/70 00:00 | |

| I would give this a try... | 01/01/70 00:00 | |

| Very useful (but still some confusion) | 01/01/70 00:00 | |
| Some answers... | 01/01/70 00:00 | |
| Rds versus Vgsoff... | 01/01/70 00:00 | |
| Exact match | 01/01/70 00:00 | |
| But with higher Rdon | 01/01/70 00:00 | |
| Should not be important | 01/01/70 00:00 | |
| Which one? | 01/01/70 00:00 | |

| Ri versus Rds(on)... | 01/01/70 00:00 | |
| Higher Rd(on) affects Ri? | 01/01/70 00:00 | |
Rd(on) versus gain | 01/01/70 00:00 |
