    摘要: A preamplifier providing adequate boost even to weak and small input currents, and thus achieving favorable gain and signal-to-noise ratio. An input current is converted to a voltage, which is provided to a differential amplification section. A phase-adjusted version of that voltage signal also is provided to the differential amplifier, the differential amplifier thus outputting an amplified signal based on the phase difference between its inputs. The preamplifier may be incorporated on a single chip, using MOS transistors or gallium arsenide techniques. A level clamping device may be provided in the event that the input current exceeds a predetermined value. The inventive preamplifier also may be incorporated advantageously into a waveform shaping circuit.

    摘要: A bipolar memory of a construction having high immunity from soft error attributable to alpha rays is provided. The transistors of a flip flop, i.e., the essential circuit of the memory cell, are inverted, and the load device thereof has a shielding arrangement for shielding the flip flop from the noise produced within the substrate. Either pnp type transistors or Schottky barrier diodes are employed as the load devices. A buried layer (ordinarily, an n type layer) and a doped layer of the reverse conductivity type (ordinarily the p type) are formed in the region where the device is provided. A reverse bias is applied across the buried layer and the doped layer to shut off the noise produced within the substrate.
