how to improve bandwidth?

[Ramakrishna47]

hi all of you,
i am using nauta"s transconductor in my filter.
Nauta"s transconductor having very less BW .
is there any methods to improve band width?

I don`t know which BW you consider as "very less", however, there is a bachelor thesis that describes an integrator based on a Nauta-transconductor which operates in the GHz range.

hi lvw,

i am talking about 3db bandwidth.
it is around 16M at capacitive load 30f F.Before capcitance i have put the transmission gate.
so total ckt becomes discrete time OTA.
for that ckt i want to improve 3db bandwidth.
is there any methods?

Requiring other edaboard members to google what you are talking about isn't rather inviting?

Would you like to guess how many edaboard members have heard about Nauta"s transconductor?
