Patent attributes
A continuous time linear equalization (CTLE) circuit is disclosed. The CTLE circuit includes an input port, an output port, a first differential transistor pair coupled to the input port and the output port and a second differential transistor pair. The CTLE circuit further includes a first degenerative impedance circuit coupled between the first differential transistor pair and ground. The first degenerative impedance includes switchable components to vary impedance of the first degenerative impedance circuit. The CTLE circuit also includes a second degenerative impedance circuit coupled between the second differential transistor pair and ground. The second degenerative impedance includes switchable components to vary impedance of the second degenerative impedance circuit, wherein the resistive part of the impedance of the first degenerative impedance circuit is equal to the impedance of the second degenerative impedance circuit.
