Abstract:
1. A CML to CMOS converter comprising: two current sources both connected between a first power supply, having a first potential, and a driving node, first and second push-pull drive stages each having a current path connected between a second power supply, having a second potential, and the driving node, and each having a control input for one half of a CML signal and an output node, wherein each of the two output nodes is connected to the control node of a respective one of the current sources, each current source being connected to decrease the current it supplies to the driving node if the potential of its respective output of the converter moves towards the potential of the first power supply wherein each push-pull stage comprises a PMOS transistor having a current path connected between the second power supply and the respective output node and an NMOS transistor connected between the respective output node and the driving node and wherein each push-pull stage comprises a capacitor connected between the respective control input and at least one of the gates of the PMOS and NMOS transistors of the push-pull stage.
