Abstract:
A signal transmitter block formed as part of an integrated circuit, said transmitter block for transmitting digital signals to a receiver, said block comprising:a plurality of signal drivers, each for generating output voltages at a signal driver output, that when measured relative to a ground point on said integrated circuit are representative of digital HI and LO signals;a first reference driver, for generating at a first reference output, one ofa. an output voltage that when measured relative to said ground point, corresponds to a voltage representative of a digital HI signal; andb. an output voltage that when measured relative to said ground point corresponds to a voltage representative of a digital LO signal;said first reference driver and said signal drivers electrically interconnected to said ground point on said integrated circuit block,said ground point interconnected through an impedance on said integrated circuit block to a system ground connection for said integrated circuit, so that current flowing from and to said system ground connection through said ground point to said signal drivers and said first reference driver flows through said impedance.
