Techniques For Low Power Analog, Digital And Mixed Signal Cmos Integrated Circuit Design, Chuang Zhang

LSU Doctoral Dissertations

With the continuously expanding of market for portable devices such as wireless communication devices, portable computers, consumer electronics and implantable medical devices, low power is becoming increasingly important in integrated circuits. The low power design can increase operation time and/or utilize a smaller size and lighter-weight battery. In this dissertation, several low power complementary metal-oxide-semiconductor (CMOS) integrated circuit design techniques are investigated. A metal-oxide-semiconductor field effect transistor (MOSFET) can be operated at a lower voltage by forward-biasing the source-substrate junction. This approach has been investigated in detail and used to designing an ultra-low power CMOS operational amplifier for operation at …
