Low Noise Linear and Wideband Transconductance Amplifier Design for Current-mode Frontend
2014 (English)Conference paper (Refereed)
A low-noise transconductance amplifier (LNTA) aimed at current-mode (Saw-less, Software-define radio) wideband receiver frontend is presented. In this application, the LNTA operates with a capacitive load to provide high linearity and sufficient G<;sub>m<;/sub> gain over a wide frequency band. By combination of various circuit techniques the LNTA, which is designed in 65 nm CMOS, achieves in simulation the noise figure in range [1-1.34] dB and linearity of maximum IIP3 = 16.5 dBm over 0.5-6 GHz band. The maximum transconductance G<;sub>m<;/sub> = 12.9 mS, the return loss S11 <; -10 dB while the total power consumption is 4 mW for 1.2 V supply.
