We present design aspects and techniques for millimeter-wave circuits implemented in 65-nm CMOS. Different transmission line topologies are discussed and measurement results for a conventional coplanar waveguide and slow-wave coplanar waveguide implemented in 65-nm CMOS are shown. The attenuation of the on-chip transmission lines can be reduced by using(More)
A base-station receiver, which is capable of receiving from one to four adjacent WCDMA channels, is described in this paper. The receiver is designed to drive high-resolution Nyquist-rate A/D converters and it can be used as a direct-conversion receiver (DCR) or as a low-IF receiver in WCDMA bands I-III. The low-IF NF is 2.7/3.0 dB for the channels centered(More)
This paper describes design issues related to high linearity SiGe BiCMOS active mixers, which are primarily targeted for WCDMA base-station applications. The effect of different mixer components to overall mixer dynamic range is described, and the measurement results from four different implementations are given to support this discussion. The different(More)
