AMS/RF-CMOS circuit design for wireless transceivers

AMS/RF-CMOS circuit design for wireless transceivers

Mobile phones have evolved from ''simple'' devices allowing phone calls over a wireless link to ''all-in-one'' devices. Besides keeping us always best connected, handheld devices have become true multimedia centers where we can watch movies or our favorite team's soccer game while making a phone call or chatting over the internet. Hence, in mobile terminals, multi-standard capability is to be s...

Millimeter-Wave Circuit Design for Radar Transceivers

New techniques for efficient flexible wireless transceivers in nanometer CMOS

Nanometer CMOS processes have proven to be surprisingly effective for analog and RF design. New design techniques have greatly improved the efficiency of ADCs and RF interfaces and also enabled new flexibility. Moving to techniques that are more digital in nature allows fast and easy changes in architecture and performance. Furthermore, from the standpoint of energy efficiency there can be fund...

Cmos Oscillator Circuit Design

Spintronic oscillators are nanodevices that are serious candidates for CMOS integration due to their compactness and easy frequency tunability. For a crystal oscillator to work, there must exist a feedback path with properly What practical circuits do is design such that we have a phase-shift of 180. A double balanced down conversion oscillator mixer using 90 nm CMOS technology is proposed in a...

Towards High Speed and Bandwidth Efficient CMOS Wireless Transceivers

We describe an approach to constructing an all-CMOS wireless transceiver capable of transmission speeds of up to 30 Mb/s in the 2.4 GHz ISM band. To achieve robust high bandwidth efficiency communications, the design includes such features as a four element antenna array, adaptive equalization, multi-level QAM transmission, variable baud rates, frequency hopping, and adjustable transmission pow...
