Abstract
This article proposes a multi-mode wireless trans-
mitter for full-duplex (FD) and half-duplex (HD) operation based
on a quadrature balanced switched-capacitor power amplifier
(QB-SCPA) architecture in 65 nm CMOS. The QB-SCPA pro-
vides inherent passive transmit–receive (TX–RX) isolation along
with an embedded digital self-interference cancellation (SIC)
signal injection mechanism and exhibits excellent TX and RX
linearity characteristics. To minimize noise figure degradation
to the RX path, local
