An efficient design of 45-nm CMOS low-noise charge sensitive amplifier for wireless receivers

Abstract: <p>Amplifiers are widely used in signal receiving circuits, such as antennas, medical imaging, wireless devices and many other applications. However, one of the most challenging problems when building an amplifier circuit is the noise, since it affects the quality of the intended received signal in most wireless applications. Therefore, a preamplifier is usually placed close to the main sensor to reduce the effects of interferences and to amplify the received signal without degrading the signal-to-noise … Show more

“…A technique which has less phase noise but with more power consumption using a differential VCO [14]. The low noise circuits are designed with higher performance to improve the signal integrity [15], [16]. A bulk driven keeper technique based current starved ring VCO is introduced to minimize phase noise and power consumption [17].…”
