Assignee: QUALCOMM INCORPORATED
Field: Basic communication processes (Electrical engineering)
Classification: CPC H | IPC H

Claim 18:
19. An method of operating an ultra wideband (UWB) communication apparatus, the method comprising:
outputting, by pulse generation circuitry, a plurality of transmission (TX) pulse samples at a selected signal sample rate, wherein each pulse sample of the plurality of TX pulse samples comprises a value associated with a pulse amplitude at a corresponding sample time;
configuring a plurality of power amplifier (PA) cells between an on state and an off state, wherein each PA cell of the plurality of PA cells comprises a corresponding current source and associated gates; and
setting the on state or the off state for each PA cell of the plurality of PA cells using logic circuitry coupled between the pulse generation circuitry and the plurality of PA cells during the corresponding sample time for the value, wherein the pulse amplitude at the corresponding sample time is associated with a number of the plurality of PA cells in the on state at the corresponding sample time as set by the value.
