ft vs fmax
(f_tau) vs (f_{max}) A device designer tweaks transistor and optimizes (f_tau) whereas an IC designer tweaks circuit and optimizes (f_{max}). But why are there two different metrics, and which one should you use? What is the difference between (f_tau) vs (f_{max})? Let’s dive right in. What is (f_tau)? The concept of (f_tau) was introduced by […]
