OPA4354: Wide Bandwidth 90 Degrees Phase Shifter Amplifiers

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.

    Hi

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

  • In reply to hasmukh kabariya:

    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.
