[sdiy] Designing Analog ICs

[karl dalen]

It would be very nice to have a new OTA to play around with.
 
* SO8 package.
* Everything temperature compensated, gain cell and control expos.
* Dual serial OTA cell with high impedance + and - input.
* High current drive output.
* Virtual summing input for gain control current and signal.
* Virtual current summing input for differential stage saturation.
* Virtual summing input for point of phase reversal.
* 20Mhz Bw at full gain, but 1Mhz will do for audio.
* Low power.
* Trimless design.
* High rejection of current control on out and in's.
* Cleverly done chip floor planing so PCB design are not mocked about.

Lucid dream but  with that you could build anything. How much effort are really needed to design that?
The market would be a lot bigger for this kind of IC then a ASIC synth or audio IC and life span would 
be considerably longer and it could be used anywhere in a vast number of applications.

Dave Rossum have nice patent for a ota/expo made for CMOS processes.

Besides im pleased, i managed to repair my flat screen SMPS, these are so creepy to deal with
several thousands volt in the backlighter cold catode lamps and 240VC AC switched primary fly-back
strange and difficult to measure for failures while not under nominal load.I dont like high voltages
they spark to much!
