Low Voltage Design Techniques and Considerations for Integrated Operational Amplifier Circuits
نویسنده
چکیده
The pertinent literature on low voltage Operational Amplifiers is surveyed and techniques suitable for operation at low power supply voltages are identified. Designs implemented in standard Bipolar, BiCMOS, and CMOS technologies are classified and characterized. The lower limit of the power supply voltage is identified as well as the performance tradeoffs that are sacrificed as that limit is approached. The three aforementioned technologies are compared quantitatively and qualitatively.
