Abstract:
1. A differential current amplifier with high frequency boost comprising: a first input line; a second input line; a first output line; a second output line; a first set of input transistors connected in parallel having the drains connected to said first input line and the sources connected to ground, said first set of input transistors comprising at least one transistor; a first resistor connected to said first input line and the gates of said first set of input transistors; a first set of output transistors connected in parallel having the gates connected to said first input line, the sources connected to ground, and the drains connected to said first output line, said first set of output transistors comprising at least one transistor; a second set of input transistors connected in parallel having the drains connected to said second input line and the sources connected to ground, said second set of input transistors comprising the same number of transistors as said first set of input transistors; a second resistor connected to said second input line and the gates of said second set of input transistors, said second resistor having substantially the same resistance as said first resistor; and a second set of output transistors connected in parallel having the gates connected to said second input line, the sources connected to ground, and the drains connected to said second output line, said second set of output transistors comprising the same number of transistors as said first set of output transistors.
