Abstract
A balanced amplifier is disclosed as comprising an input stage connected with a second stage, in which the input stage outputs signals to the second stage, and the first stage includes a first differential amplifier for receiving balanced input signals and is provided with two pairs of feedback loops, at least one of the pair of feedback loops for feedbacking part of signals outputted by the second stage to the first differential amplifier, and the second stage includes a second differential amplifier for amplifying signals received from the first stage and for maintaining the balanced signals.
Claims21
A balanced amplifier comprising at least an input stage connected with a second stage, wherein said input stage is adapted to output signals to said second stage, wherein said first stage includes a first differential amplifier adapted to receive balanced input signals and is provided with two pairs of feedback loops, wherein at least one said pair of feedback loops are adapted to feedback part of signals outputted by said second stage to said first differential amplifier, and wherein said second stage includes a second differential amplifier adapted to amplify signals received from said first stage and is adapted to maintain said balanced signals.
A balanced amplifier substantially as herein described and with reference to FIGS. 1 to 6B.
