Abstract

This 2 GHz monolithic Si-bipolar logarithmic/limiting amplifier introduces a waveform-dependent current phase shifter that compensates the intrinsic dependence of unit-amplifier phase shifts on input signal amplitudes and uses layout techniques that minimize cross-talk in Si substrate. The amplifier dissipates 250 mW at 3 V supply, less than 1/4 of that of previously reported high-frequency ICs. The RSSI dynamic range is 60 dB and the limited-output phase deviation is less than 7/spl deg/ at 2 GHz.
