ABSTRACT:
A signal converter with a dynamically adjustable reference voltage according to the invention, which can receive different qualities of signals. The signal converter includes an input circuit and a reference voltage generator. The input circuit converts a first digital signal, such as a GTL+ signal, into a second digital signal, such as a TTL or CMOS signal, based on an adjustable reference voltage generated by the reference voltage generator. When a control circuit needs to receive the first digital signal from outside via the input circuit, the control circuit can adjust the reference voltage by controlling the reference voltage generator so as to receive the first digital signal with a different quality.
