1–10GHz inductorless receiver in 0.13µm CMOS

In this paper, we describe an inductorless wideband radio receiver architecture from 1 GHz to 10 GHz. 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, comparable noise figure and uses only 17% more power. The silicon area for the CPLM is only 22% of the IPLM. Both designs can be mated with an inductorless, ring-oscillator based, wide lock range and low power PLL also shown in this paper.
