In one example, a driver circuit includes a differential transistor pair configured to be biased by a current source and including a differential input and a differential output. The driver circuit further includes a resistor pair coupled between a node pair and the differential output, a transistor pair coupled between a voltage supply and the node pair, and a bridge transistor coupled between the node pair. The driver circuit further includes a pair of three-state circuit elements having a respective pair of input ports, a respective pair of control ports, and a respective pair of output ports. The pair of output ports is respectively coupled to the node pair. The pair of control ports is coupled to a common node comprising each gate of the transistor pair and a gate of the bridge transistor.

System and method for controlling one or more switches. The system includes a first converting circuit, a second converting circuit, and a signal processing component. The first converting circuit is configured to convert a first current and generate a first converted voltage signal based on at least information associated with the first current. The second converting circuit is configured to convert a second current and generate a second converted voltage signal based on at least information associated with the second current. The signal processing component is configured to receive the first converted voltage signal and the second converted voltage signal and generate an output signal based on at least information associated with the first converted voltage signal and the second converted voltage signal.

In a switching device and a system for converting a differential input signal into a ground-referenced output signal using a control signal, error states are detected, and detected error states lead to the deactivation of the ground-referenced output signal and are indicated on the control signal in addition.

A CML to CMOS signal conversion system includes a CML/CMOS converter coupled to a resistor, which is further coupled to a current compensation circuit at a reference node. The CML/CMOS converter receives a differential signal and applies a first or a second current to the reference node through the resistor. The current compensation circuit comprises a differential transistor pair coupled to a current source, a transistor, and a first, a second, and a third current mirror. The differential transistor pair receives the differential signal and has a pair of output terminals. The first current mirror is coupled to the output terminals. The third current mirror is coupled to the reference node. The first and third current mirror are coupled together by the transistor and sink the first current. The second current mirror is coupled to the output terminals and the reference node and sinks the second current.

Methods and apparatus are described for a differential active inductor load for inductive peaking in which cross-coupled capacitive elements are used to cancel out, or at least reduce, the limiting effect of the gate-to-drain capacitance (C.sub.gd) of transistors in the active inductor load. The cross-coupled capacitive elements extend the range over which the active inductor load behaves inductively and increase the quality factor (Q) of each active inductor. Therefore, the achievable inductive peaking of the load is significantly increased, which leads to providing larger signal swing across the load for a given power or, alternatively, lower power for a given signal swing.
