By applying on-chip linear VRM, PDN inductance is greatly decreased and PDN resonance peak disappears, which is usually generated by PCB/PKG inductance and on-chip capacitance. To confirm, we design an application circuits which have on-chip linear voltage regulator module (VRM) with aggressor and victim buffer. We validate the advantages of on-chip linear VRM by measuring fabricated chip in this...
On-chip voltage regulator module (VRM) for the reduction of power/ground noise on power distribution network (PDN) and jitter minimization at high-speed output buffer is introduced. The basic topology and optimized operation for on-chip VRM is analyzed. A PDN with on-chip VRM shows reduced power/ground noise through removing additional effects coming from package/PCB PDN. Also, when on-chip VRM is...
