Yield-Ensuring DAC-Embedded Opamp Design Based on Accurate Behavioral Model Development
نویسندگان
چکیده
An accurate behavioral model of a DAC-embedded opamp (DAC-opamp) is developed for a yield-ensuring LCD column driver design. A lookup table for the V-I curve of the unit differential pair in the DAC-opamp is extracted from a circuit simulation and is later manipulated through a random error insertion. Virtual ground assumption simplifies the output voltage estimation algorithm. The developed behavioral model of a 5-bit DAC-opamp shows good agreement with the circuit level simulation with less than 5% INL difference. key words: DAC, DAC-embedded, behavioral model, yield

Digital Offset Calibration of an OPAMP Towards Improving Static Parameters of 90 nm CMOS DAC
In this article, an on-chip self-calibrated 8bit R-2R digital-to-analog converter (DAC) based on digitally compensated input offset of the operational amplifier (OPAMP) is presented. To improve the overall DAC performance, a digital offset cancellation method was used to compensate deviations in the input offset voltage of the OPAMP caused by process variations. The whole DAC as well as offset ...

This paper presents a resistance matching based selftestable current-mode R-2R Digital-to-Analog Converter (DAC). The Built-In Self-Test (BIST) circuits are employed to observe the current redistributions in the resistance matching branches converted from the R-2R network in the DAC, and then the redistributed currents are transformed to voltages to detect the R-2R network with extra Design For...
متن کاملConsiderations for Accurate Behavioral Modeling of High-Speed SC ΣΔ Modulators
The performance of Σ∆ Modulators (Σ∆Ms) is highly dependent of that of their embedded switched-capacitor (SC) network. Therefore, detailed transient models of SC integrators become necessary when modeling Σ∆Ms. This work presents a behavioral transient model of a SC integrator that includes the effects of the amplifier transconductance and output conductance relation; and the dynamic capacitive...
