Abstract: A single power supply common-gate (CG) current mode transimpedance preamplifier (TIA) is developed with a 0.5μm GaAs PHEMT process.The amplifier has a measured -3dB bandwidth of 7.5GHz and a transimpedance gain of 45dBΩ.Both the input and output voltage standing wave ratios (VSWR) are less than 2 within the bandwidth.The equivalent input noise current spectral density varies from 14.3 to 22pA/Hz,with an average value of 17.2pA/Hz.Having a timing jitter of 14ps and eye amplitude of about 138mV,the measured output eye diagram for 10Gb/s NRZ pseudorandom binary sequence (PRBS) is clear and satisfactory.

Key words: GaAs PHEMT, current mode, preamplifier, noise figure, eye diagram
