概要

• 論文の詳細を見る

• A 2-GHz monolithic Si-bipolar logarithmic/limiting amplifier is described. It features a waveform-dependent current phase shifter that compensates for the intrinsic dependence 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 deg. at 2GHz. Therefore, this amplifier is quite suitable for single-conversion transceivers for broadband wireless access systems.
