Abstract
A low power differential receiver input stage using n-channel/p-channel transistor pairs to adjust the voltage levels of differential output signals. A first n-channel/p-channel transistor pair is connected to a first output terminal and a second n-channel/p-channel transistor pair is connected to a second output terminal. First and second differential signals respectively applied to first and second input terminals are passed to the first and second output terminals through first and second resistors, respectively. The first differential signal is applied to the gates of the second n-channel/p-channel transistor pair, thereby adjusting the voltage level at the second output terminal. Similarly, the second differential signal is applied to the gates of the first n-channel/p-channel transistor pair, thereby adjusting the voltage level at the first output terminal.
