Between the metal–insulator–metal (MIM) capacitor and metal–oxide–metal (MOM) capacitor, the MIM capacitor has a better characteristic of stable capacitance. However, the MOM capacitors can be easily realized through the metal interconnections, which does not need additional fabrication masks into the process. Moreover, the capacitance density of the MOM capacitor can exceed the MIM capacitor w...

A capacitor-free CMOS low-dropout (LDO) regulator for system-on-chip (SoC) applications is presented. By adopting AC-boosting and active-feedback frequency compensation (ACB-AFFC), the proposed LDO regulator, which is independent of an off-chip capacitor, provides high closed-loop stability. Moreover, a slew rate enhancement circuit is adopted to increase the slew rate and decrease the output v...

DC-offset and DC-suppression are key parameters in bioelectric amplifiers. However, specific DC analyses are not often explained. Several factors influence the DC-budget: the programmable gain, the programmable cut-off frequencies for high pass filtering and, the low cut-off values and the capacitor blocking issues involved. A new intermediate stage is proposed to address the DC problem entirel...
