Signal Sources, Conditioners and Power Circuitry Circuits of the Fall, 2004 &mdash AN98
PDF, 886 Kb, File published: Nov 19, 2004
Eighteen circuits are presented in this compilation. Signal sources include a voltage controlled current source, an amplitude/frequency stabilized sine wave oscillator, a versatile, 0V to 50V wideband level shift and four sub-nanosecond pulse generators with risetimes as low as 20ps. Five signal conditioners appear; a unique, single positive rail powered amplifier with output to (and below) zero volts, a milliohmmeter, a 0.02% accurate instrumentation amplifier with 120dB CMRR at 125VCM, a 100MHz switch with 5mV control channel feedthrough and a 5V powered, 15ppm linearity quartz stabilized V→F, converter. The power circuits section features a Xenon flashlamp supply, two 5V powered, 0V to 300V DC/DC converters, a fixed 200V output circuit for APD bias, a 100W 0V to 500V, 28V powered converter and a high current paralleling scheme for linear regulators. Two appended sections consider measurement technique and connection practice in sub-nanosecond circuits.

Introduction
Occasionally, we are tasked with designing circuitry for a
specific purpose. The request may have customer origins
or it may be an in-house requirement. Alternately, a circuit
may be developed because its possibility is simply too
attractive to ignore1. Over time, these circuits accumulate,
encompassing a wide and useful body of proven capabilities. They also represent substantial effort. These considerations make publication an almost obligatory proposition
and, as such, a group of circuits is presented here. This is
not the first time we have displayed such wares and, given
the encouraging reader response, it will not be the last2.
Eighteen circuits are included in this latest effort, roughly
arranged in the categories given in this publicationвЂ™s title.
They appear at the next paragraph.
Voltage Controlled Current SourceвЂ”Ground Referred
Input and Output
A voltage controlled current source with ground referred
input and output is difficult to achieve. Executions exist,
but are often cumbersome, involving numerous components. Figure 1вЂ™s conceptual design utilizes a differential …
