提出了一种包括自干扰（SI）消除电路和谐波抑制功率放大器（HPA）的低功率无线电模拟前端，以减少发射机（TX）和接收机（RX）之间的相互作用，从而实现全双工操作。台积电原型器件在4MHz带宽上实现了超过30dB的SI消除，PA三次和五次谐波分别降低了30dB和15dB。该电路的有源面积为131×112.5μm2，在1.2V电源电压下功耗为0.25mW，接收噪声衰减小于0.6dB。
A low-power radio analog front-end which includes a self-interference (SI) cancellation circuit and a harmonic-rejection power amplifier (HRPA), is proposed to reduce the interaction between a transmitter (TX) and receiver (RX), to enable full-duplex operation. A prototype TSMC device demonstrates more than 30dB SI cancellation over a 4MHz BW and a PA 3rd and 5th harmonic reduction of 30dB and 15dB, respectively. The SI cancellation circuitry occupies an active area of 131×112.5μm2, consumes 0.25mW from a 1.2V supply and degrades the RX NF by less than 0.6dB.
