current mirror




"BUT FIRST you will see the wilderness
and give it your own meaning" he said.
It will proceed your heart and will
continue afterward
Know this above all:
what you save in the lightning
will last pure forever."

This is why we need diaphaneity.
In order to discern knots along
the thread which streched through
the centuries, helps us to stand
upright on this earth.

Odysseas Elytis

* it has infinite AC impedance, while a practical mirror has finite impedance
* it provides the same current regardless of voltage, that is, there are no compliance range requirements
* it has no frequency limitations, while a real mirror has limitations due to the parasitic capacitances of the transistors
* the ideal source has no sensitivity to real-world effects like noise, power-supply voltage variations and component tolerances.

II en est un plus laid, plus méchant, plus immonde!
Quoiqu'il ne pousse ni grands gestes ni grands cris,
Il ferait volontiers de la terre un débris
Et dans un bâillement avalerait le monde;

C'est l'Ennui! L'oeil chargé d'un pleur involontaire,
II rêve d'échafauds en fumant son houka.
Tu le connais, lecteur, ce monstre délicat,
— Hypocrite lecteur, — mon semblable, — mon frère!

— Charles Baudelaire
