This paper describes the design of a low-voltage CMOS rail-to-rail operational amplifier. We have designed input signal compression circuitry that compresses rail-torail input signals to the input range of the following foldedcascode operational amplifier, which is capable of rail-to-rail output. The input signal compression circuitry and the following(More)
This paper presents a new technique for accurately modeling uni-directional High-Voltage lightly-doped-drain MOS (HV MOS) devices by extending the bi-directional HV MOS model and adopting a new parameter extraction method. We have already reported on a SPICE model for bi-directional HV MOS devices based on BSIM3v3. However, if we apply this bi-directional(More)
