A 900-MHz CMOS Bandpass Amplifier for Wireless Receivers
This dissertation describes the design of a CMOS 900-MHz bandpass amplifier that is suitable for RF transceivers. The work employs the state-of-art inductive degeneration techniques to minimize the noise figure and explores the use of lossy spiral inductors in high frequency circuit to realize input matching networks on-chip. A Q-compensation circuit is included to achieve a 25-MHz 3-dB bandwid...
متن کاملDesign of High Efficiency Power Amplifier for RFID Readers
In RFID reader systems, power amplifier plays a critical rule for efficiency enhancement. A high efficiency power amplifier may not only increase the life expectancy of portable RFID devices but also reduce the reliance on heat sinks. Heat sinks usually occupy plenty of space and lead to packing difficulties. A well-designed power amplifier with high efficiency and output power may also increas...

متن کاملA 2.45 GHz 30dBm differential 0.18 μm CMOS class-E power amplifier with 42% PAE
This paper presents a 30dBm (1W) class-E power amplifier projected in a standard 0.18-μm CMOS technology. The power amplifier (PA) consists in two differentials stages. The main stage employs a cascode class-E RF power amplifier with a self-biasing circuit. The driver stage uses the technique of Injection-Locking to substantially reduce the input power signal, maintaining a high gain. At 2.45 G...
متن کاملThe Design of a 3-V 900-MHz CMOS Bandpass Amplifier
A new bandpass amplifier which performs both functions of low-noise amplifier (LNA) and bandpass filter (BPF) is proposed for the application of 900-MHz RF front-end in wireless receivers. In the proposed amplifier, the positive-feedback Q-enhancement technique is used to overcome the low-gain lowQ characteristics of the CMOS tuned amplifier. The Millercapacitance tuning scheme is used to compe...
