A Novel down Conversion Mixer with Low/High Band Re-configurable Transconductance Amplifier in 65nm CMOS ProcessPublished in Institute of Electrical and Electronics Engineers Inc.
2021
A 100MHz-5GHz down conversion mixer is reported for a multistandard wireless receiver with universal transconductance amplifier having reconfigurability in the form of RF band-width. In the proposed architecture RF bandwidth reconfigurability is reconfigured between low band (LB) RF frequency and high band (HB) RF frequency mixer modes. LB/HB reconfigurability is made through PMOS/NMOS switching the transconductance amplifier between these two modes. The proposed circuit is designed in UMC 65nm RFCMOS technology with 1.2V supply voltage. The circuit employs no inductors and operates from 100M-600M in LB and 600M-5G in HB. From the simulation results, the proposed circuit shows conversion gain of 35.4/27 dB, noise figure of 9/12.6 dB and IIP3of-7.1/5.5 dBm in HB and LB respectively. The inductorless circuit can operate over a wide frequency range. Hence this circuit will be much helpful in multi-standard receiver design. © 2021 IEEE.
