... GENERAL DESCRIPTION The PKD01 tracks an analog input signal until a maximum amplitude is reached. The maximum value is then retained as a peak voltage on a hold capacitor. Being a monolithic circuit, the PKD01 offers significant performance and package density advantages over hybrid modules and discrete designs without sacrificing system versatility ...

... When the moving pole is considered with the typical frequency compensation of voltage amplifiers however, there is a loop stability problem. The necessary compensation can increase the required acquisition time. ADI’s approach replaces the input voltage ampli- fier with a transconductance amplifier (see Figure 2). The PKD01 transfer function can be reduced to OUT ...
