Hi all,

Could anyone tell me what is a Low Vt , High Vt and dual Vt transistor what are their advantages and when they are used.
Any material document or plots will be highly appreciated.

Thanks in advance for your replies.
 

High Vt guarantees low leakage current(thus low power consumption) and robust logic
while low Vt is usually benefit for analog circuit in view of voltage swing (thus dynamic range).

Added after 4 minutes:

Dual Vt combine both advantage of them,thus suit for mixed signal design.
Besides some pure digital system also use dual Vt to release the trade-offs between the speed and power.
