I'm available for projects

Started by Jim Thompson May 12, 2016
I sit here bored out of my skull with nothing to do but play Solitaire
until the next project start on July 5 ;-)

I'm noted for custom Analog/Mixed-Signal Design and Spice Behavioral
Modeling, but I also do designs using off-the-shelf components.

No project is too small... I've even done one-day designs from
time-to-time.

I love to cook with wine.     Sometimes I even put it in the food.

How about writing that book I've been bugging you about?

I ponder that, but I'm not sure I'd be good at writing... circuit design is so easy for me I'm not sure I can explain how I do it ;-) ...Jim Thompson -- | James E.Thompson | mens | | Analog Innovations | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | San Tan Valley, AZ 85142 Skype: Contacts Only | | | Voice:(480)460-2350 Fax: Available upon request | Brass Rat | | E-mail Icon at http://www.analog-innovations.com | 1962 | The touchstone of liberalism is intolerance

Do you freeze when walking, then frantically start drawing in the dirt with a stick, like this poor Croatian did? :D https://books.google.com/books?id=N59vRqVTcm8C&pg=PT98&lpg=PT98&dq=tesla+teacher+said+impossible+build#v=onepage&q=tesla%20teacher%20said%20impossible%20build&f=false Michael

Worse... I dream circuits and wake myself up, then can't get back to sleep ;-) ...Jim Thompson -- | James E.Thompson | mens | | Analog Innovations | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | San Tan Valley, AZ 85142 Skype: Contacts Only | | | Voice:(480)460-2350 Fax: Available upon request | Brass Rat | | E-mail Icon at http://www.analog-innovations.com | 1962 | The touchstone of liberalism is intolerance

As long as the circuit isn't lost, it's a gain, right? Sometimes I would dream of music in my sleep, wake up, and want to write the notes down, but in the transition to wakefulness they're lost :p Michael

Start with some examples, and write them as you go along. I find that writing or rewriting sections when I'm actually doing the task described improves them greatly.

In the mid 1980s, Roland had International Rectifier design a custom chip called the IR3R05 for their analog synthesisers. I think it was a 14 pin package...it basically consisted of 4 OTA stages like the Lm13700 configured as a 24 db/octave resonant low pass filter with inputs for voltage controlled frequency and resonance, along with a VCA with both linear and exponential inputs, all on the chip. The 4 filter capacitors were mounted off chip on the board. What kind of job would it be to design a chip or maybe a daughterboard that performed an equivalent function? These chips often fail in vintage equipment and there seems to be a decent sized market for replacements that dont require scrounging for NOS or cannibalizing old units. -- ----Android NewsGroup Reader---- http://usenet.sinaapp.com/

I'm sure I could replicate the chip, but I don't do PCB layout, that's another skillset altogether. ...Jim Thompson -- | James E.Thompson | mens | | Analog Innovations | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | San Tan Valley, AZ 85142 Skype: Contacts Only | | | Voice:(480)460-2350 Fax: Available upon request | Brass Rat | | E-mail Icon at http://www.analog-innovations.com | 1962 | The touchstone of liberalism is intolerance
