چکیده
This paper hearsay a unique cross-coupled current conveyor based cmos transimpedance amplifier with series inductive peaking design to achieve an input capacitive load insensitive, low noise and augment the bandwidth of transimpedance amplifier. The peaking inductor is in series with the capacitor constituting a dominant pole. It boosts the band width of the amplifier.The whole transimpedance amplifier consumes 225.90μW of the dc power measured results show a -3dB bandwidth of about 6.7GHz with a 0.25pF photodiode capacitance. The trnsimpedance gain for positive output port is 50.9 dBΩ . The measured single ended input referred noise current spectral density is kept underneath 4.4159pA/√Hz within the TIA frequency band. The series inductive peaking network consists of inductor at the input to resonate with CD near the -3dB bandwidth of the amplifier, reduces input referred noise and increase the overall bandwidth.
