Abstract:
A new method for power amplification is proposed. By studying the N-path filter structure, the N-path Structure is employed for power amplifier design. The main feature of this method is that the power amplifier designed upon this structure can amplify the input signal in a multi-standard fashion. In addition, N-path structure eliminates the matching network at the output of power amplifier which usually is a complex circuit implemented off-chip. At the first step, mathematical relations are employed in order to find the appropriate structure for the power amplifier and efficiency optimization is done by means of new mathematical relations. In the next step, required blocks are designed for a power amplifier which is capable of amplification for both 802.11g and 802.11n standards. This step includes presenting a new structure for output switches and design of baseband amplifiers and clock generation circuit
