Wideband frontend in a receiver

A receiver, comprising:

• an analog front-end (AFE) having an input coupled to a transmission medium through a capacitor;
• and
• a termination coupled to the input of the AFE;
• a first circuit configured to supply a voltage to the termination, the first circuit comprising:
• a second circuit coupled to a current source through a first resistor;
• first and second inverters coupled between a supply voltage and a first node between the first resistor and the current source;
• second and third resistors;
• first and second transistors, gates of the first and second transistors coupled to outputs of the first and second inverters, respectively, drains of the first and second transistors coupled to a second node, sources of the first and second transistors coupled to a third node through the second and third resistors, respectively;
• wherein the second circuit is coupled to the third node and the second node is configured to supply the voltage to the termination.
