opamp questions:<\/h2>\n

– why matching input stage transistors.<\/p>\n

– advantages\/disadvantages to pnp\/npn.<\/p>\n

– is most the noise from the input stage.<\/p>\n

– how to get rail to rail output.<\/p>\n

– what affects unity gain stability.<\/p>\n

– what affects gain linearity.<\/p>\n

– where does the distortion mostly come.<\/p>\n

– advantage to high hfe in input.<\/p>\n

– what affects max voltage.<\/p>\n

– what is best type of current mirror.<\/p>\n

– what affects slew rate.<\/p>\n

 <\/p>\n

opamp design:<\/h2>\n

simulate:<\/strong><\/p>\n

– do a 990 layout with the that input chip.<\/p>\n

– try number of stage config.<\/p>\n

– try an API alike.<\/p>\n

 <\/p>\n

breadboard:<\/strong><\/p>\n

– any simulations that work.<\/p>\n

 <\/p>\n

layout:<\/strong><\/p>\n

990 Style<\/p>\n

 <\/p>\n

Tryout:<\/strong><\/p>\n

try the opamps in the sontec and nseq, and mic pre.<\/p>\n
