The objective of this report is to clarify the output resolution of a buck converter employing digital delta-sigma-modulation (DSM) control. The output resolution of a DC-DC converter with DSM control can be evaluated quantitatively through its effective number of bits (ENOB). The improvements in ENOB by a DSM multibit technique and
a related idle-tone suppression by a pseudorandom number sequence and converter output feedback are investigated both theoretically and experimentally.The digital DSM control system is implemented on an FPGA system in VHDL. |
