hello,
Can someone help and guide me to design third-order OTA-C type filter using cadence? the below attachment is i found from somewhere abt gm-C filter but i dont know the OTA in transistor-level simulation model...
hope anyone who have experience to design it to help me..(urgent!!!)
thanks a lot....
 


Hi jlim.
my recommendation: First try to become familiar with basics of filter topologies.
You intend to design a 3rd order filter - and at the same time, you are not yet able to recognize if a circuit diagram is a filter or an amplifier only ?
 

Ok..thanks for your suggestion...
do you have any recommendation or reference for this kind filter in transistor-level model??
 

hello,i have using cadence to design the basic OTA but i cnt get the correct ac response...
How to determine the value for Vin+,Vin- and Vbias?
