Typical Power supply value for 0.18um Technology for TransImpedance Amplifier
Aug 03^rd, 2011, 7:19pm

Hello All,
Could someone pls tell me the typical VDD value for a highspeed >2.5GHz transimpedance amplifier(Inductor free)? I am embarking on a self project and want to make sure i am using typical value for my power supply. Is 2V an OK value?
May i add also what a typical value for the input diode capacitance might be.

Hi,

Its mainly determined by the stress that the devices can handle. I think 0.18 um technology is typically 1.8 V and 3.3 V for high voltage devices. 2 V may cause long term stress issues especially for digital circuits.

Not sure about input diode capacitance...probably need to check some publications, or if possible, manufacturer data.

regards,
Aaron
