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.....

Zeolites are microporous crystalline aluminosilicate molecular sieve that have pore sizes ranging from about 0.3 to 1 mm. Due to their uniform, molecular-sized pores, they can separate molecules based on their size, shape and polarity. They can therefore act as ''molecular sieves''. Membranes made o.....

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.....

A novel endoscopic imaging system for diagnosis of early cancer is described. Optical spectroscopy has been widely used in chemical analysis of biological samples. Since the mid-80s, the use of this technology for tissue classification has become a new approach in non-invasive medical diagnostics......
