| Περίληψη: | This work presents a wideband switchless Front-End (FE) which contains a two-stage power amplifier (PA) and a two-stage low noise amplifier (LNA). The linearity of the PA is the focus of the work in the transmitter side (TX) and is improved by adopting a stacked configuration with an adaptive bias technique. The adaptive bias improves the output compression point (O1dB) by nearly 5 dBm. A driver is placed before the output stage of the PA to ensure wideband operation and higher gain. The LNA consists of two-stage single ended configurations and uses the current steering architecture to provide extended reconfigurable operation. Both LNA and PA are connected to the antenna through a passive structure called duplexer which provides optimum noise and power matching at each side with low losses and minimum area occupation. The process used for the design is TSMC’s 40nm bulk CMOS and all the simulations are post layout extracted. The design covers a 3-dB bandwidth of 11 GHz from 22.7 to 33.8 GHz and presents linearity of 18 dBm for the TX and a noise figure (NF) of 4.5 dB for the RX part with 20.7 dB gain. |

| gkoutis2020.pdf | This paper presents a (transceiver) TRX front-end structure design for Phased Array applications in 40nm CMOS Bulk process. The proposed structure consists of the Power Amplifier (PA) the Low Noise Amplifier (LNA) along with a monolithic transformer duplexer for Antenna connection applied in half-duplex systems. The front end covers the millimeter wave (MMW) 5G band. The PA design contains two differential cascode stages with capacitor neutralization technique achieving a small signal gain (S21) of 22.86dB with a -3dB bandwidth (BW) at 22-34 GHz. Moreover, the PA reaches a PAEmax of 31.66% and a Psat of 18.5 dBm. The LNA design consist of two cascode stages using current reuse technique at the first stage, obtaining 17.5 dB gain (S21) with a -3 dB bandwidth from 22.5 to 31 GHz. Both amplifiers are connected to the antenna through a compact duplexer with minimum losses and sufficient isolation. | 446.96 kB | Adobe PDF | - |  | Δείτε/ανοίξτε |
