I'm trying to model a discrete component filter being driven by an AD8138, through the filter, and into an LTC2153-14 ADC. I don't have those active components in the sim, just the discrete components, along with their parasitics. While the filter shape is what I expect, it peaks at greater than 0dB no matter how I try to model it, and that is nonsensical. Is there a recommended way to drive a circuit like this differentially and then retrieve the output, also differentially?PN8303_BPF.asc
