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

Claim 0:
1. An ultra wideband (UWB) communication apparatus, comprising:
pulse generation circuitry configured to output 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;
a plurality of power amplifier (PA) cells, each PA cell of the plurality of PA cells comprising a corresponding current source and associated gates, wherein the associated gates of each PA cell are selectable to configure the PA cell between an on state and an off state; and
logic circuitry coupled between the pulse generation circuitry and the plurality of PA cells, the logic circuitry configured to set the on state or the off state for each PA cell of the plurality of PA cells during the corresponding sample time for the value, and 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.
