Ultra-wideband impulse radio transmitter with modulation

A transmitter with modulation, comprising:

• a phase changing stage configured to receive a phase changing signal, the phase changing signal including at least one first state and at least one second state different from the at least one first state;
• the phase changing stage comprising
• at least one first switch;
• at least one second switch coupled to the at least one first switch;
• at least one first transistor coupled to the at least one first switch;
• and
• at least one second transistor coupled to the at least one second switch;
• wherein the at least one first switch is configured to operate in an opposing manner to the at least one second switch such that only the at least one first transistor is configured to be turned on in the at least one first state and only the at least one second transistor is configured to be turned on in the at least one second state upon receipt of the phase changing signal by the at least one first switch and the at least one second switch so as to achieve a change in an output phase of the transmitter when the phase changing signal switches from the at least one first state to the at least one second state.
