In this paper, we describe an inductorless wideband radio receiver architecture from 1GHz to 10GHz. Two receiver RF frontends designs are presented and compared: a traditional inductor peaking LNA and mixer (IPLM) and a capacitive peaking LNA and mixer circuit (CPLM). Measurement results indicate that CPLM with the same bandwidth has better linearity,(More)
Inductors are used in RF design to extend the bandwidth by resonating out the load and/or parasitic capacitance. However, on-chip inductors are large and cannot be ported easily from one process to the next. Due to modern CMOS scaling, inductorless RF design is becoming possible. In this paper we describe a new methodology for designing the RF frontends(More)

Faraday cages have traditionally been used to provide isolation from electromagnetic fields. In this paper, we describe the use of Faraday cages for reducing crosstalk in 3D ICs. We validate our methodology with a combination of simulation and measurements from fabricated prototype designs. Measurement and simulation results show that the crosstalk between(More)
