A new switched-opamp technique is proposed to operate switched-capacitor circuits at supply voltages as low as 1-V without on-chip voltage multiplier or low-Vt devices. The main idea of the new switched-opamp technique is to implement an additional switchable operational amplifier (opamp) in parall.....

Power management is necessary to reduce standby power consumption of low-power portable applications such as mobile phones and personal digital assistants (PDAs). A low-dropout regulator (LDO) is a type of voltage regulator that is widely utilized in power management integrated circuits. In order to.....

It is very difficult to shield low frequency sound waves. This is mainly because in order to cause wave scattering or reflection, the usual wisdom is that the size of the scatterers must be on the order of the wavelength. Since low frequency sound has long wavelength, it follows that the shielding m.....
