Issue Date: | 2015 | Publisher: | 0026-2692 | Journal: | Microelectronics | Abstract: | Inductors are used extensively in Radio Frequency Integrated Circuits to design matching networks, load circuits of voltage controlled oscillators, filters, mixers and many other RF circuits. 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 rapidly becoming possible. In this paper a new methodology for designing the RF frontend necessary for the DVB-SH in a 90 nm CMOS technology based on the use current conveyors (CC) is presented. The RF frontend scheme is composed of a second generation CC (CCII) LNA with asymmetric input and output, an asymmetric to differential converter, and a passive differential mixer followed by two CCII transimpedance amplifiers to obtain a high gain conversion. Measurements show a conversion gain of 20.8 dB, a 14.5 dB noise figure, an input return loss (S11) of −14.3 dB and an output compression point of −3.9 dBm. This combination draws 28.4 mW from a ±1.2 V supply. | URI: | http://hdl.handle.net/10553/45458 | ISSN: | 0026-2692 | DOI: | 10.1016/j.mejo.2015.04.003 | Source: | Microelectronics Journal[ISSN 0026-2692],v. 46 (3829), p. 581-587 |
