Abstract
An amplifier circuit includes a continuous-time linear equalizer, an adjustable gain circuit and a filter circuit. The continuous-time linear equalizer includes a first high-pass path, a first low-pass path, a second high-pass path, and a second low-pass path. The first high-pass path is used to increase a gain of a high-frequency part of a first signal source, and the second high-pass path is used to increase a gain of a high-frequency part of a second signal source. The filter circuit is used to amplify and filter the first signal source and the second signal source, and includes a fully-differential operational amplifier, a first filter network, and a second filter network.
