    摘要： Semiconductor charge devices are defined to effect a serial-to-parallel conversion of analogue signal information. In one aspect of the invention, a digital signal is extracted from an analogue noise environment by a shift register correlator comprising a bucket-bridge configuration of field-effect transistors in combination with gating field-effect transistors which are effective to weight the amplitude of the data in corresponding bits of the shift register. The gates of the gating transistors are selectively connected to diffused regions of transistors of the bucket-brigade delay line to effect parallel tapped outputs therefrom. The weighted signals from the gating transistors are summed at a common terminal to form the auto-correlated output. In a different aspect of the invention, the analogue delay line is effected by a charge-coupled shift register, parallel taps being obtained from diffused regions under selected electrodes of the shift register ohmically connected to gates of the gating field-effect transistors.

    摘要： A current driver circuit using a two-level current source for switching PIN diodes. The driver is responsive to a binary signal control voltage for providing a respective forward-bias current or reverse-bias voltage. The two-level current source, responsive to output voltage, is included in the driver circuit to supply one of two current levels when the driver is conditioned to forward-bias the diode. When the output voltage is below a predetermined threshold value, a first level of current is supplied; when the output voltage is above the predetermined value, a second level of current, generally larger than the first current, is provided. The disclosed technique reduces peak instantaneous power dissipation in the driver by avoiding the simultaneous condition of high voltage and high current.

    摘要： An improved current switch emitter follower (CSEF) latch has reduced "noise" in the output signal from equal and opposite operation of the output transistors. The improvement resides in dotting the collector resistors of the input transistors in each current switch with a common shift resistor. The dotted collector resistors control the output transistors whereby one turns on and the other turns off with little change in output signal level as clock signals change to the input transistor.

    摘要： A high frequency FM signal is divided by a parametric frequency divider to develop at an output, a low frequency FM signal. The divider includes a graded junction varactor diode and performs divisions in excess of 100 with good linearity. The divided down signal is within an optimum response range for recording or applying the signal to an audio recording means, such as a magnetic tape.
