Digitally Assisted Mixed-Signal Circuit Security

Mixed-Signal Simulation of Digitally Controlled Switching Converters

In this paper we give an overview of tasks, models and mixed-signal simulation tools to support design of digitally controlled switching power supplies where the digital controller is implemented in a dedicated FPGA or ASIC. Mixed-signal simulation models of a digitally controlled switching converter based on Matlab/Simulink and HDL/Spice simulation tools are presented. The models are used in t...

DesignCon 2007 Digitally Assisted Adaptive

This paper describes a production-worthy adaptive equalizer used for integrating a transceiver on an FPGA. Since FPGAs are required to support a wide customer base, it is desirable to have a design flexible enough to adapt to different types of backplanes, drivers and data rates. This is extremely challenging since the data rate of the transceiver varies from 622 Mbps to 6.5 Gbps. The goal of t...

Testing of embedded A/D converters in mixed-signal circuit

In this paper, a complete functional testing of embedded ADC is presented. The integral non-linearity error, INLE, differential non-linearity error, DNLE, offset error, OSE, gain error and the signal-to-noise ratio, SNR are tested. The problem related to the propagation of the analog signal to the input of the ADC and the observation of the digital output of the converter at the output of the d...
