A Fully Integrated Compact Outphasing CMOS Power Amplifier Using a Parallel-Combining Transformer with a Tuning Inductor Method

Fully Integrated CMOS Power Amplifier

A fully integrated 2.45 GHz 0.25μm CMOS power amplifier

A fully integrated differential class-AB power amplifier has been designed in a 0.25um CMOS technology. It is intended for medium output power ranges such as Bluetooth class I, and has an operating frequency of 2.45GHz. By using two parallel output stages that can he switched on or off, a high efficiency can be achieved for both high and low output power levels. The simulated maximum output pow...

Low Power Amplifier Design Using CMOS Active Inductor

In this paper, a CMOS low power amplifier based on a high-quality active inductor and implemented by using 0.25-μm 1P5M CMOS standard technology is presented. The amplifier achieves power gain (S21) of 18dB within the -3dB cutoff frequency, bandwidth of 1.3GHz, and power consumption of 18mW under 2.5V power supply in 188 × 174μm silicon area. The input third-order intercept point (IIP3) and the...

A 28-36 GHz Optimized CMOS Distributed Doherty Power Amplifier with A New Wideband Power Divider Structure

Background and Objectives: In this paper, a new design strategy was proposed in order to enhance bandwidth and efficiency of power amplifier. Methods: To realize the introduced design strategy, a power amplifier was designed using TSMC CMOS 0.18um technology for operating in the Ka band, i.e. the frequency range of 26.5-40GHz. To design the power amplifier, first a power divider (PD) with a ver...

A 20 GHz fully-integrated power amplifier in a 0.13 μm CMOS process

Research Projects Agency, grant # DAAB07-02-1-L28. In large part because of their guidance, this project was interesting and challenging, enabling me to hone my technical proficiency in integrated circuits while here at Berkeley. My fellow graduate students have provided me with the best possible support for intellectual development and social interaction, particularly Through all the exhilarat...
