Splet31. maj 2024 · The impact of 3-T (3-Terminal) decoupling capacitors on PDN (Power Delivery System) in LPDDR4/4X/5 system is presented. The main advantage of 3-T caps over traditional 2-T caps is their reduced ESL (Equivalent Series Inductance). This reduced ESL leads to lower PDN impedance and hence improved PI (Power Integrity) and eye …
SpletThe inductance of bond wires spanning from the semiconductor die, the package lead frame, and any bonding pads on the die and package all have some inductance. This inductance creates the voltage spikes seen on I/Os when groups of I/Os switch together.
