A gated integrator, using standard analog computing amplifiers, is described. Because of the
placement of the diode gate within the feedback integrating loop, many of the previous …

A current integrator is described which will integrate currents in the range 10-10 to-5
ampere. It is shown that the circuit is inherently capable of a better performance than …

A simple circuit that can be used to improve the signal-to-noise (SIN) ratio of a repetitive
signal is described. Major simplifications in the circuit design are achieved by use of the …

An instrument is described which combines a current integrating circuit and a dc amplifier to
provide a continuous indication of the current being integrated. The instrument is stable …

This fast, low-current integrator uses an active feedback circuit to eliminate the effects of
reset/offset error and switch leakage. Sensitivity is 200 pC per volt, response time is< 1 ps …

A simple, inexpensive, two‐channel gated (``boxcar'') integrator circuit using solid state
components is described. Features of the circuit include a wide range of usable gate widths …

The design of an inexpensive``boxcar''integrator for improving the signal‐to‐noise (S/N)
ratio of low level repetitive signals is described. The design is simplified by using the timing …

A current integrator has been built in which a servo is used to charge a capacitor in discrete
amounts so as to match within certain limits the integral of an input current. By keeping the …

A current integrator employing a neon bulb has been used; it is found to require no
correction of any kind, and to be independent of power supply fluctuations. The lowest …

A new data‐acquisition and averaging system is described which rapidly digitizes and
averages periodic signals of known frequency. Each acquisition channel has a …
