Analytic Sampling-Circuit Model

June 1, 2001
Author(s)
Dylan F. Williams, Catherine A. Remley
Abstract: We develop analytic expressions for the impulse response and kickout pulses of a simple sampling circuit that incorporate the nonlinear junction capacitance of the sampling diode. We examine the effects of both the time-varying junction

A Method to Compare Vector Nonlinear Network Analyzers

May 1, 2001
Author(s)
Kate Remley, Donald C. DeGroot, Jeffrey Jargon, Kuldip Gupta
We address the difficult problem of determining measurement consistency between two vector nonlinear network analyzers, a new class of stimulus-response instruments that acquire multiharmonic waveform data instead of normalized network parameters. We

Effects of Nonlinear Diode Junction Capacitance on the Nose-to-Nose Calibration

May 1, 2001
Author(s)
Kate Remley, Dylan Williams, Donald C. DeGroot, Jan Verspecht, John Kerley
We examine the effects of nonlinear diode junction capacitance on the fundamental premise of the noise-to-nose calibration, that the kickout is identical in shape to the impulse response of the sampler. We offer a physical explanation for the error

Realistic Sampling-Circuit Model for a Nose-to-Nose Simulation

June 1, 2000
Author(s)
Catherine A. Remley, Dylan F. Williams, Donald C. DeGroot
We extend previously developed oscilloscope sampler models to include realistic circuit characteristics and use these models to investigate the nose-to-nose calibration technique.

Nose-to-Nose Response of a 20-GHz Sampling Circuit

December 1, 1999
Author(s)
Dylan F. Williams, Catherine A. Remley, Donald C. DeGroot
We use SPICE simulations to determine a response function of a two-diode 20-GHz sampling circuit. We explore the validity of the SPICE simulations in a variety of operational conditions and examine differences between the actual response of an impedance
