Level Shifting in CMOS
Hello
Question about level shifting in CMOS
Would you use a source follower everywhere or just resize tranistors so that the VDS changes and then changes your common mode levels ?
I have heard source followers in CMOS are garbage (poor gain, frequency response) and plus CMOS does not have the built in VBE that bipolar does.
application is current steering logic but also any other CMOS interconnection block.
Any thoughts or experience in this ?
