A 0.9GHz–5.8GHz SDR receiver front-end with transformer-based current-gain boosting and 81-dB 3rd-order-harmonic rejection ratio
A 0.9GHz-to-5.8GHz SDR RFE is presented employing a dual-band LNA with a switchable 3-coil transformer as loading for current-gain boosting and an automatic LO phase-error detection and calibration circuitry for harmonic rejection. Fabricated in 65nm CMOS and integrated with a fully-integrated all-digital synthesizer (ADFS), the RFE measures NF between 2.9dB and 3.8dB, IIP3 between -1.6dBm and -12.8dBm, 3rd-order HRR of 81dB, and 5th-order HRR of 70dB, while consuming between 66mA and 82mA from a 1.2V and occupying a total chip area of 4.2 mm2.
