A Reconfigurable CMOS Inverter-based Stacked Power Amplifier with Antenna Impedance Mismatch Compensation for Low Power Short-Range Wireless Communications

Design of Low-Power CMOS Limiting Amplifier Using Negative Impedance

In this paper we design the low-power CMOS limiting amplifier using negative impedance, the purpose of using negative impedance is to increase the gain of the amplifier. low-power operations are also done using all the active elements. The LA was implemented in a standard CMOS 0.18um technology. This limiting amplifier is designed for the instrumentation(bio-medical) application. Gain of the am...

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...

Low Power Low Noise CMOS Chopper Amplifier

AbstractChopping is a proficient way to reduce the low frequency offset and 1/f noise in amplifiers. In this paper, a low power low noise CMOS chopper amplifier is presented. It is composed of a two stage amplifier. The first stage’s high output impedance and the equivalent Miller capacitance of the second stage constitute together a low pass filter, which reduces the power consumption. The cir...
