For mobile applications, SIC should be linear, tunable, fully monolithic (compact form factor) and must be implemented at the radio-frequency (RF) front-end. Emulating the group delay (GD) and complex impedance of the SI channel, an SIC circuit is proposed that achieves an 80 MHz of SIC BW using just a single tap delay. GD is estimated using frequency translations and baseband (BB) low pass filtering, and complex impedance is emulated using a vector modulator (VM). We prove that the combination of GD and VM results in a time-domain Hilbert transform equalization (HTE), enabling broadband cancellation and reducing the number of GD taps needed, thereby saving area. Implementing HTE at BB using passive circuits further reduces area, power consumption and maintains linearity. A prototype in 0.13-µm CMOS process occupies 0.4 mm2 and attains 23 dB of SIC measured over an 80-MHz signal BW, while consuming 13 mW.
