0.6V, 5dB NF, −9.8dBm IIP3, 900MHz receiver with interference cancellation

We present an integrated 900MHz receiver with 56.4dB conversion gain, 5dB NF, and -9.8dBm IIP₃ using on-chip in-band feed-forward interference cancellation. The interference cancellation at baseband gives more than 13dB IIP₃ improvement and makes operation from an ultra-low 0.6V supply possible. The direct-conversion receiver including baseband filters and polyphase LO filters and buffers consumes 26.4mW from a 0.6V supply and occupies 2.56mm² in a low power 65nm CMOS process.
