A Large-Signal Blocker Robust Transimpedance Amplifier for Coexisting Radio Receivers in 45nm CMOS Conference Paper uri icon


  • A baseband transimpedance amplifier for coexisting radio receivers is presented. It exploits active feedback to improve out-of-band large-signal attenuation, minimizing in-band distortion due to close-in blockers. A fully-differential prototype of the proposed solution has been designed and implemented in 45nm CMOS. Experimental results show that it can handle linearly single tones of 10mA, withstanding blocking currents of 9mA at 50MHz and beyond before reaching P1dB in a 10MHz bandwidth. The fabricated device occupies 0.25mm2, largely MOM finger capacitors, and draws 17mA from a 2.5V supply. 2011 IEEE.
