Topic: IEEE Life Fellow Paul Brokaw - Sheerluck Ohms and the 33dB solution
<br />
<br />
This talk will present a simple arrangement which makes a robust class A power stage using a bipolar output transistor. The voltage gain of the stage will be shown to be quite stable over a range of outputs, supply, and loads. Devotees of the great detective will recognize the allusion to a smaller amount of quite another sort of solution. The X-Files Fox Mulder isn't available to make this presentation, so you will have to settle for me describing a circuit which can be thought of as a modification of the improved version of George Wilson's current mirror. It involves an X connection of the bases or gates depending on the technologies you have available. It's not a mirror, but rather has a (surprising?) property that lends itself to several small but powerful circuits.
