Part Number: OPA4354

Hi,

I am trying to design a 90 degree phase shifter circuit like http://www.ti.com/corp/docs/university/pdf/adc2012_politecnico_di_milano.pdf

need help to decide component value? Is there is any IC available which can perform same task?

Hi,

Are you asking what values to use for the resistors in the circuit? I am unfortunately not aware of any IC that performs a phase shift in this manner.

Regards,

I have given link where you can find same operation, unfortunately i am confuse in selection of MOSFET

Hi,

For the MOSFET, do you mean the switches used in the circuit? Unfortunately I was not able to find any more information on this particular project, but the switch selection will depend on exactly what frequency range you are targeting.
