An FTNC receiver with +32.5dBm effective OB-IIP3 using baseband IM3 cancellation
An IM3 cancellation technique is proposed and implemented in a 65nm CMOS 0.5–2.5GHz FTNC (frequency translational noise-cancelling) receiver with a wideband auxiliary path which also offers wideband interferer awareness. It achieves 8.8MHz BB BW, 40dB conversion gain, 3.3dB NF, +5dBm OB-IIP3, and −6.5dBm OB-B1dB without IM3 cancellation while consuming 36mW at 1.2V. Using IM3 cancellation, the equivalent OB-IIP3 for two-tone interferers is up to +32.5dBm with an extra 34mW of power consumption. For two −15dBm modulated interferers 18.8dB cancellation is demonstrated over 10MHz.
