How do ICs with FET push/pull outputs avoid shoot through?
Hi - I've been trying to work this out in my head... Let's say you have an IC that has a FET push/pull output. So I suspect that they have a complementary pair of FETs on the...

Calculating MOSFET gate charge
I've been trying to better my understanding of MOSFET characteristics. I figure that's a fairly important skill to have. So - I'm trying to see if I can derive and understand some...

Switching high voltage (5KV+)
Howdy folks - in the near future I may need to build a circuit that switches on/off a high voltage (5-10KV) load. I can switch either the high or the low side. Current will be in...

sockets for leaded discretes
Hi - I'm looking to make a very configurable PCB test board. Specifically, I want to be able to plug discrete components into it quickly and easily. Does anybody know of any...

Using multiple diodes in series to increase voltage rating
How legit is this? I had always assumed that it wouldn't work, as you couldn't guarantee that the diodes had the same voltage drop across them (due to manufacturing variations) -...

How to generate a slightly negative voltage?
Howdy - I need to generate a supply that is just slightly negative. Like I only need -.25V or so. A bit more would be fine - but not much. Certainly no more than -1V. It will be...

calling those that know logic chips
Hi - I need to find a schmitt trigger buffer or inverter. It needs to be able to handle a 3.3V level input, but have a 5V output. Ideally there'd be a family with a wide range of...

Where to buy scope probe connector?
Hi - I'm looking to pick up a PCB mount scope probe connector. What, you say? Yeah, I have no idea what they're called. They're little vertical connectors that allow you to plug a...

Mega ceramics
I want some really freaking huge ceramic capacitors. I'm working on a 6.6A, 43V DC/DC boost converter that is operating at 1MHz - and I want as little ripple as possible. That...

How does thermal cycling affect Lithium polymer cells?
Howdy - I can't seem to find much good information regarding lithium polymer cells. I've had to piece together little bits and pieces from all over the Internets. What I'm curious...

How to speed up this high side FET driver
Hi there - I'm working on a high side FET driver for a 1MHz boost converter. The simulation of it looks... OK. Not as bad as it could be, but certainly not good. I've attached a...
