Dynamic amplifier of large output swing
A dynamic amplifier includes a common-source amplifier configured to receive a gate voltage at a gate node and output a drain current to a drain node; a current mirror configured to mirror the drain current into an output current to an output current; a source capacitor connected to the source node;...

| Zusammenfassung: | A dynamic amplifier includes a common-source amplifier configured to receive a gate voltage at a gate node and output a drain current to a drain node; a current mirror configured to mirror the drain current into an output current to an output current; a source capacitor connected to the source node; a load capacitor connected to the output node; a first switch configured to conditionally connect the gate node to an input voltage; a second switch configured to conditionally connect the gate node to a gate-resetting voltage; a third switch configured to conditionally connect the source node to a source-resetting voltage; a fourth switch configured to conditionally connect the drain node to a drain-resetting voltage; and a fifth switch configured to conditionally connect the output node to an output-resetting voltage. |
