Practical Circuitry for Measurement and Control Problems &mdash AN61
PDF, 1.1 Mb, Datei veröffentlicht: Aug 1, 1994
This collection of circuits was worked out between June 1991 and July of 1994. Most were designed at customer request or are derivatives of such efforts. Types of circuits include power converters, transducer signal conditioners, amplifiers and signal generators. Specific circuits include low noise amplifiers, high power single cell DC/DC converters, portable high accuracy barometers, a 10mHz 1% accuracy RMS/DC converter, and random noise generators. Appended sections cover noise theory and present a historical perspective of wideband amplifiers.

Practical Circuitry for Measurement and Control Problems
Circuits Designed for a Cruel and Unyielding World
Jim Williams
INTRODUCTION currents associated with the continuous operation of fixed
frequency designs. Gated oscillator regulators simply
self-clock at whatever frequency is required to maintain
the output voltage. Typically, loop oscillation frequency
ranges from a few hertz into the kilohertz region, depending upon the load. This collection of circuits was worked out between June
1991 and July of 1994. Most were designed at customer
request or are derivatives of such efforts. All represent
substantial effort and, as such, are disseminated here
for wider study and (hopefully) use.1 The examples are
roughly arranged in categories including power conversion, transducer signal conditioning, amplifiers and signal
generators. As always, reader comment and questions
concerning variants of the circuits shown may be addressed
directly to the author. In most cases this asynchronous, variable frequency operation does not create problems. Some systems, however, are
sensitive to this characteristic. Figure 1 slightly modifies
a gated oscillator type switching regulator by synchronizing its loop oscillation frequency to the systems clock. In
this fashion the oscillation frequency and its attendant
switching noise, albeit variable, become coherent with
system operation. Clock Synchronized Switching Regulator …
