摘要：

A 2-GHz monolithic Si-bipolar logarithmic! limiting amplifier is described, it features a waveform-dependent current phase shifter that compensates for the intrinsic dependent of unit-amplifier phase shifts on input signal amplitudes and layout techniques that minimize crosstalk in Si substrate. The amplifier dissipates 250mW at a 3-V supply, which is less than 1/4 of that of previously reported ICs., The dynamic range of a received signal strength indicator (RSSI) is 60dB and the limited-output phase deviation is less than 7 dee. at 2 GHz. Therefore, this amplifier is quite suitable for single-conversion transceivers for broadband wireless access systems.
