    verilog flash adc

    how do you code an ADC in verilog? I know it is possible to code an DAC in verilog by using PWM but not sure how to do ADC. Can somebody help me?

    verilog adc real

    ADC is mostly implemented with analog circuit(r-2r adc,flash adc)... so not possible to write verilog code

    Re: ADC in verilog

    D/A converters are typically compact and easier to design. Why not do A/D convert using a D/A converter and a comparator using op_amps?D to A generates analog voltage which is compared to the input voltage. If D to A voltage > input voltage then set that bit; otherwise, reset that bit. This type of A to D takes a fixed amount of time proportional to the bit length

    Re: verilog flash adc

    when we code a DAC in verilog, the PWM signal is not an analog one it is a digital signal with 1 bit. that'is it?

    Hi all,
    Can any one help me how can i code a thermometer-coded DAC based on current sources with VHDL?
