Abstract :
A 65-nm CMOS limiting amplifier based on three stages of a modified Cherry-Hooper amplifier with offset cancellation is presented. The trade-off between the offset cancellation range and input-referred noise is discussed. The variations on gain and bandwidth due to PVT corners are presented. The limiting amplifier achieves 32.1 dB gain and 21.6 GHz bandwidth, with a 1-V supply and a power dissipation of 33.3 mW.
