Input (protection) FET or npn
Hi all a simple input circuit take a input pulse. And stretches it a bit. (from previous post on pulse stretching.) The input looks like this.. (bad asci art) +5V +--------+ | R(1M) _ ---+ ^ | | | |/c...

Qualcomm in talks to acquire NXP
This is getting downright confusing. Freescale sold their stuff to NXP. NXP sold its old RF power transistors to Ampleon. Analog Devices buys Linear Tech. The article said that the consolidation is...

More inductor talk, Proximity effect, self capacitance
A fine gentleman did an experiment building two inductors. The coils were wound with 420/46 litz. Both inductors have 40 turns. One inductor is close wound (215uh 7.7pf distributed capacitance). The...

beads and zero ohm resistors
Has anyone measured the resistance and tempco of cheap surface-mount zero-ohm resistors? Has anyone measured the resistance tempco of surf-mount ferrite beads? How are those constructed anyhow? I...

Gate resistor for lateral power MOSFET?
I'm designing a power amplifier using some Exicon lateral MOSFETs as the final common-source stage. These will be used in various experimental systems. Each only needs to run around +/-50V out, up to...

PCB heater
I was thinking that I could thermally isolate a small patch of a PCB ground plane, about one square inch, and add some resistors as heaters to make sort of a local oven for the parts above the patch,...

Another Mystery Chip
I also find myself in possession of 7 CMP02Es. All I can find out is that they are Precision Monolithics comparators but have been out of production so long that I can not find any datasheets or pin...

Switching large currents
I have a current leak on my car that I can't trace. I've tried taking all the fuses out one by one to identify the circuit causing the problem but whatever I do, the vehicle is draining 50mA 24/7 when...

current monitor
I want to measure some power rail currents on a PC board, part of self-test, and it looks like I could use a shunt resistor and an INA199. It's fairly cheap and second-sourced by ON. Any thoughts?
