Abstract:
A method is provided for receiving a differential signal pair input at a first circuit stage and converting the differential signal pair input to a single-ended signal at a second circuit stage. The method also provides for receiving an output of the first circuit stage and an output of the second stage at a third circuit stage and transmitting an amplified signal output from the third circuit stage. The method allows for a 60 dB signal gain or more. A circuit is also provided that includes multiple circuit stages that can provide signal gain to an input differential signal pair. The circuit converts the differential pair into a single-ended signal and transmits the amplified signal as an output. The circuit provides the signal gain without using a current mirror. A computer readable storage device encoded with data for adapting a manufacturing facility to create an apparatus is also provided.
