Transimpedance Amplifier Based on Inductive Peaking Techniques for Broadband Data Transmission
A cross-coupled current conveyor base transimpedance amplifier implemented to obtain the input capacitance load insensitivity effect is introduced. The proposed architecture is designed using 0.12μm 1.2-V technology with on-chip spiral inductor as shunt peaking element and parasitic element are compensated for achieving high gain at minimum tailored input. The measured results show a -3dB bandwidth of about 11.5 GHz with a 0.25 pF photodiode capacitance and transimpedance gain of implemented circuit is 55.5dBΩ. The architecture provides very low power dissipation, reduced by 58% which is most important factor as it can be used in cascade configuration where its output is fed to another system.
