A 2-GHz 60-dB Dynamic-Range Si Logarithmic/Limiting Amplifier with Low Phase Deviations
Summary :
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 250 mW 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 60 dB and the limited-output phase deviation is less than 7 deg. at 2 GHz. Therefore, this amplifier is quite suitable for single-conversion transceivers for broadband wireless access systems.
