A Concurrent Dual-Band Low Noise Amplifier for GNSS Receivers

In this paper, a new design of concurrent dual-band Low Noise Amplifier (LNA) for multi-band single-channel Global Navigation Satellite System (GNSS) receivers is proposed. This new structure is able to operate concurrently at frequency of 1.2 and 1.57 GHz. Parallel and series resonance parts are employed in the input matching in order to achieve concurrent performance. With respect to used pse...

A 1.2v Improved Operational Amplifier for Bio- Medical Applications

In recent years, there is an ever-growing demand for low-power and low-noise mixed signal integrated circuits for applications such as portable medical systems. A high level of system integration is required to implement bio-potential system with mixed signal circuits. The most commonly observed bio-potentials used for medical diagnoses are monitored non-invasively with electrodes placed on the...

A Dynamic Instrumentation Amplifier for Low-Power and Low-Noise Biopotential Acquisition

Abstract: A low-power and low-noise dynamic instrumentation amplifier (IA) for biopotential acquisition is presented. A dynamic IA that can reduce power consumption with a timely piecewise power-gating method, and noise level with an alternating input and chopper stabilization technique is fabricated with a 0.13-μm CMOS. Using the reconfigurable architecture of the IA, various combinations of t...

A Reconfigurable CMOS Low Noise Amplifier for Wireless LAN Applications

This paper presents the designed and implemented CMOS Low Noise Amplifier (LNA) for multiband operation in TSMC 0.18 m process. To operate in multibands and multistandards, switched inductor and switched capacitor array are used in input and output signal paths. Due to filtering characteristic of input stage, the LNA can suppress spurious signal effectively. The designed reconfigurable LNA is t...
