Claim Text:
1. An amplifier comprising: a first mixed-length MOS (metal-oxide semiconductor) device set for receiving an input signal and outputting an output signal; and a first load for providing termination for the output signal, wherein the first mixed-length MOS device set comprises a parallel connection of a plurality of MOS devices having different channel lengths including at least a short channel length MOS device and a long channel length MOS device, wherein the channel length of the long channel length MOS device is longer than the channel length of the short channel length MOS device, wherein the plurality of MOS devices includes a first MOS transistor and a second MOS transistor, and the parallel connection is defined by a source terminal of the first MOS transistor being directly connected to a source terminal of the second MOS transistor and a drain terminal of the first MOS transistor being directly connected to a drain terminal of the second MOS transistor.
