Abstract:
A circuit for generating a differential signal between first and second outputs in response to first and second input signals comprising:a first charge pump having first and second inputs and a charging current source and a discharging current source, said first input of said first charge pump connected to said first input signal to engage said charging current source to increase said differential signal at said first output, and said second input connected to said second input signal to engage said discharging current source to decrease said differential signal at said first output, anda second charge pump having first and second inputs and a charging current source and a discharging current source, said first input of said second charge pump connected to said first input signal to engage said charging current source to increase said differential signal at said second output, and said second input connected to said second input signal to engage said discharging current source to decrease said differential signal at said second output.
