Term
CMOS inverter - what is the total charge when a transistor charge an Cap load?
Definition
E = CL*VDD
Term
CMOS inverter -  What is the energy injected?
Definition
Einj = VDD * Q = CL*VDD^2
Term
CMOS inverter - what is the energy dissipated when chargin a cap load?
Definition

Ediss = Vavg * Q = (CL*Vdd^2)/2

 

(heat)

Term
CMOS inverter - what is the energy stord in the cap laod?
Definition
CMOS inverter - Einj - Ediss = (CL*VDD^2)/2
Term
what is the formula for dynamic power?
Definition

P = f*x*VDD^2*CL

 

several nodes

P = f*VDD^2*sum(x*CL) 

Term
how can we reduce P and E?
Definition
reduce C, V, f
