scientists as superstars

That's really scary, science as a path to fame, fortune, prizes, adoration from movie stars. -- John Larkin Highland Technology, Inc Science teaches us to doubt. Claude Bernard

Super duper hype fast FET driver?

Folks,Have to drive around a hundred pF or so in parallel with maybe a fewhundred ohms blazingly fast. 10-12V amplitude, transitions ideallysub-nanosecond from 10-90% both directions. Not too boutiquish orunobtanium (which excludes certain...

LEDs in parallel

I understand the points about calculating the series resistance for anLED and the battery voltage, and about using a small resistor just tobe safe even if the battery voltage is "about right" for the LED.The general advice "do not connect...

Need higher speed 2N7002

The 2N7002 has served me well for many years but at 20MHz general purpose switching the 30nS rise times are just too slow by an order of magnitude. What SMD is readily available with less internal capacity and comes close to the other...

2N7002

My data sheet for the 2N7002 is dated 1995. It's 23 years old. And it's still a really good part. Capacitances are low, it can switch over an amp, and it's really fast. There's nothing newer that can do some of the stuff it can. -- John...
