摘要： A charge coupled amplifier wherein an output voltage proportional to the difference between two input voltages is achieved through use of different value capacitances associated with the signal input and signal output structures of the amplifier. The input capacitance is defined in one embodiment using a doped substrate region beneath a biased electrode located between the signal input gates. In a modified structure, increased area input gate electrodes are used to define the input capacitance. A CCD transversal filter employing split electrode tap weighting which together with associated charge coupled input and output amplifiers form part of a single semiconductor chip.

摘要： Insulated gate field effect transistor charge regenerator amplifiers respectively cross-couple the output regions of a pair of two-phase CCD structures with the input regions of those structures. Each amplifier senses the level of binary data charge packets from the output region of one of the shift register structures and in response thereto applies a regenerated and inverted binary data charge packet to the input region of the other shift register structure. One of the amplifiers includes logic gating for inputting and outputting data into and from the shift register structure.A charge regenerator for a two-phase CCD structure comprising first and second shift registers. The charge regenerator comprises a source follower amplifier including a driver transistor, a load transistor and a positive feedback transistor connected between the gate and source of the driver transistor. The gate of the driver transistor is precharged to a predetermined level prior to sensing of the output region charge level and the regenerator inserts into the input region a charge packet corresponding to the data level sensed at the output region, without inversion.

摘要： Homomorphic speech processing apparatus utilizing CCD implementation of the CZT algorithm for performing DFT and IDFT operations in extracting representations of formants and/or pitch data from sampled speech inputs. Embodiments also are described for performing the DFT and IDFT operations (a) by generating n-transforms and averaging the result and (b) for performing a sliding CZT transform. In a further embodiment, a smoothed spectrum of vocal tract data is obtained using a CCD filter with a low pass response. The CCD implementation includes transversal filters employing split-electrode signal amplitude weighting.
