Patent ID: 8421510

Claim:
An apparatus comprising: a pulse generator having: a first differential pair of transistors that receives a first differential input signal and that outputs a first current signal; a first bias transistor that is coupled to each transistor from the first differential pair at a first node; a second differential pair of transistors that receives the first differential input signal and that outputs a second current signal; a second bias transistor that is coupled to each transistor from the second differential pair at a second node; a third differential pair of transistors that receives a second differential input signal, wherein a first transistor from the third differential pair is coupled to the first node, and wherein a second transistor from the third differential pair is coupled to the second node; a current-to-voltage (I-V) converter that is coupled to each of the first and second differential pairs so as to receive the first and second current signals; and an amplifier that is coupled to the I-V converter that generates a first output signal in response to the first current signal and a second output signal in response to the second current signal.
