… this Master Thesis has been to investigate the possibilities for a new type of noise reduction solution that could decrease the negative effects resulting from larger traffic roads. The idea has been to construct a noise barrier with a roof ? like a tunnel placed on a road. The …

Design of a Direct-conversion Radio Receiver Front-end in CMOS Technology

Examensarbete, grundnivå · Linköpings universitet

… suffers from several drawbacks such as extreme sensitivity to DC offsets, 1/f noise, local oscillator (LO) leakage/radiation, front-end nonlinearity and I/Q mismatch. This implies very high demands on the DCR front-end. The front-end comprises a low-noise amplifier (LNA) and a …
