Fabrication of electroacoustic RF amplifiers
Anodic bonding of a lithium niobate piezoelectric crystal over a silicon-on-sapphire structure with the crystal mounted over a closely controlled oxide provides a point-contact mount for two rectangular slabs /one piezoelectric and the other a silicon semiconductor/ within 600 A of each other.

Log amplifier instrument measures physiological biopotentials over wide dynamic range
To record biopotentials with extreme dynamic ranges, biopotential inputs are capacitatively coupled to a miniature, low power, solid-state signal conditioner consisting of a two-stage differential preamplifier that has a low noise figure. The ouput of the preamplifier uses diodes to provide an overall gain which is nearly logarithmic.

High current compensation network for dc logarithmic amplifiers
Circuit voltage output is reduced by voltage equivalent to ampere resistance drop of nonlogarithmic resistances of practical diodes; therefore, output is same as circuit using ideal diode. Circuit applies to meter and electronic recorder movements, and improves performance of radiation detectors and several microbiological monitoring devices

Isolated-line commutator-amplifier
Commutator device combines several individual signal-input lines into single output line. Its desirable characteristics are - low input impedances, high output impedance, very high forward-to-reverse transmission ratios, and minimal gating spike coupling to either the inputs or the output.

Amplifier for signal from thin film transducer
Electronic circuitry is devised to raise low level signal from platinum film type transducer to sufficient amplitude to trigger oscilloscope or time interval counter. Circuit can be used wherever it is necessary to raise level of low amplitude, low impedance positive polarity pulse source to a 5 or 6 volt level.
