Classification: CPC H | IPC H

Claim 0:
1. An amplifier comprising:
an input unit configured to receive a differential input signal at a first input terminal and a second input terminal;
a conversion unit comprising a first current mirror comprising a first current determiner and a first current follower configured to operate in response to a voltage or current on a first current determination and/or voltage generation node of the first current determiner, a second current mirror comprising a second current determiner and a second current follower configured to operate in response to a voltage or current on a second current determination and/or voltage generation node of the second current determiner, a first transmission gate disposed between the first current determiner and the second current determiner, and a second transmission gate between the first current follower and the second current follower, the conversion unit being configured to provide a first conversion voltage and a second conversion voltage that vary in response to the differential input signal at the input unit;
an amplification unit configured to provide an output voltage in response to the first conversion voltage and the second conversion voltage;
a frequency compensation circuit comprising a first compensation capacitor disposed between an output terminal and the first current follower and a second compensation capacitor disposed between the output terminal and the second current follower; and
a short-circuit current minimization circuit comprising a first short-circuit compensation capacitor disposed between the output terminal and the first current determination and/or voltage generation node and a second short-circuit compensation capacitor disposed between the output terminal and the second current determination and/or voltage generation node.
