ABSTRACT:
A GTL input receiver for receiving differential GTL signals and for generating a CMOS output at a single-ended output terminal includes a comparator circuit, a current-to-voltage converter circuit, and an inverter. The comparator is formed of a first primary current steering device and a second primary current steering device. Auxiliary current steering devices are coupled to the first and second primary current steering devices for adding hysteresis by dynamically changing the ratio of the currents flowing through the first and second primary current source devices. The input receiver also includes a control circuit for selectively enabling and disabling the secondary current steering devices. As a result, the GTL input receiver has a hysteresis in the range of 50 mV to 200 mV and higher.
