ViaWizards help you design mixed-signal circuits suitable for ASIC integration without having you having to be a full-custom designer. ViaDesigner is mixed-signal IC design software that runs in the cloud at www.ViaDesigner.com. The ViaDesigner app comes with a library of ViaWizards useful for creating circuits like: amplifiers, programmable gain stages, instrumentation amplifiers, fully differential op-amps, log amps, transimpedance amplifiers, analog muxes, linear regulators, buck regulators, SAR analog to digital converters, sigma delta ADCs, current steering DACs, voltage DACs, bandgap voltage references, bias generators, high voltage circuits,...(more). Explore ViaDesigner.com and get started developing mixed-signal ICs yourself. You can get to prototype via configured ASICs for ZERO NRE.
