Setting Up Shop

These are my new lab partners: Sophie, Shazer, Shule and Sally.
They are helping me set up an electronics lab at the house. My only piece of test equipment is a handheld digital multimeter but I've started designing a simple DC Voltage source which I've been collecting some components for. After building that I will make a preamp for a ribbon mic I have.

I just got way too busy to keep up with the circuit of the day postings, in place of that I'll start updating how my projects are going. School has been busy, I've found out that layout can be very time consuming but also I've been distracted by planning my own side projects, which I'm getting very interested in. Here's to playing safely with electricity!

Day 9: ESD Protection Diodes

I took the weekend off but we're back today. My schedule may prevent me from posting daily but I'll keep putting things up when I have time. Today I look at something that I've seen quite a bit as an intern in the protection division at ON Semi.

Day 8: Ideal Op-Amp with Negative Feedback

For stability and to avoid riding the rails (clipping at the op-amp +-Vcc), the feedback path impedance must not be allowed to become too large.

Day 7: PMOS Current Mirror

Day 6: Wheatstone Bridge

This question was asked in a written test in a job interview last week.

Day 5: Diode Bridge Rectifier

I love how simple yet so genius this configuration is. So many things we plug into the wall have this in it; there must be zillions of these out there.

Day 4: Damping, 2nd Order Systems

Continuation of yesterday's circuit.
