Subscriber Line Interface Circuitry Line Driver
A linefeed driver apparatus includes a first current mirror having an input leg for current IIN1 and a mirrored leg for current IMIRR1, wherein IMIRR1 varies proportionately to IIN1 with a gain of α1. The input leg and the mirrored leg of the first current mirror are coupled to provide (α1+1)IIN1 to...

| Zusammenfassung: | A linefeed driver apparatus includes a first current mirror having an input leg for current IIN1 and a mirrored leg for current IMIRR1, wherein IMIRR1 varies proportionately to IIN1 with a gain of α1. The input leg and the mirrored leg of the first current mirror are coupled to provide (α1+1)IIN1 to a driven line. The apparatus includes a second current mirror having an input leg for current IIN2 and a mirrored leg for current IMIRR2, wherein IMIRR2 varies proportionately to IIN2 with a gain of α2. The mirrored leg of the second current mirror provides α2IIN2 to the driven line, wherein α2=α1+1. |
