摘要： An integrated circuit device includes a reference voltage generator, which is configured to generate an adaptive reference voltage (Vref) that varies inversely relative to changes in magnitude of a data signal (DATA) received at an input thereof. This reference voltage generator includes a totem pole arrangement of at least two variable impedance elements having control terminals capacitively coupled (by respective capacitors) to the input. A current mirror is electrically coupled to the totem pole arrangement of at least two variable impedance elements. A comparator is also included. The comparator has a first input terminal that receives the adaptive reference voltage and a second input terminal that receives the data signal.

摘要： An apparatus having a first circuit and a second circuit. The first circuit may be configured to buffer an input signal received as a single-ended signal from a data bus connected between a memory channel and a memory controller. The second circuit may be configured to condition the input signal relative to a reference voltage to generate a differential signal. The reference voltage may be isolated from the second circuit in response to a transition from a power down condition to a power on condition.
