Hi,
I have trouble with loading .wdf wave format from spectre (aps) simulator to Custom WaveView viewer. Current signals are saved (or displayed) with port number instead port name. I must find appropriate port number in netlist. In case >30 port instance this is really annoying :-(
thanks...
Re: Folded cascode OpAmp
That I mast do to avoid structural offset in this configuration? Which transistor determine structural offset a how a eliminate it.
offset analysis of folded cascode
I am beginner in analog ic design. This materials is very difficult to understand. To date i think that all transistor in OpAmp must work in saturation region. If diff. pair transistors work in weak inversion region, Gm opapm be small?
Hi all,
Can anyone explain how design width and length of transistor in this topology or ratio (W/L) of transistor in differential pairs and mirror to get a good matching offset.
Target of design : Design of the low offset (max. 5mV) rail to rail operational amplifier in CMOS technology. OpAmp...
