    How does power sensor work?

    How does power sensor work, and what is the definition of the bandwidth of a power sensor? If I use a power sensor to measure the output power of a power amplifier, (for example I use a 5MHz WCDMA signal centered at 2GHz to stimulate the PA), the coupled power of the power sensor is the 5MHz...

    VHDL-AMS error: ADC_REF_LADDER' could not be loaded, entity may requre re-analysis

    Hi everyone! I am following the Virtuoso AMS Designer Flow to practice the the simulation of the mixed-signal circuits. The simulation project is provided by Cadence, which is vfs_amsflow. When I compile the project all the components in Verilog-AMS is compiled correctly but the only one in...

    How to embed a VHDL entity to an analog simulator?

    Hello everyone! I am now designing a successive approximation ADC as a final project. As you know this kind of ADC need a digital circuit as a controller to control some switches connected to the capacitors array. Now the situation is I dont need to implement this controller in transistor...
