Pos. fbk. Op. Amp. - (spice) noise


about LM324 , uA741 , TL071 , LM308 :









  compared to conventional biasing schemes : 


the pos.-fbk scheme has more poor noise and frequency characteristics but it enables to use the feedback shoulder to excite a crystal or reduce the input current . . .

ADC related Op.-Amp. Experiment

~about


↑↑ _ the best result here however would be Frequency × Slew Rate _ ↑↑

(( required to Drive 74HC14 's INP , AND/OR that relative to a VREF . . . basically to make power-buffer's input more sensitive & a higher impedance one))
