<p>An electrometer for sensing the output signal charge of a CCD shift register employs a bipolar static induction transistor (BSIT) to sense signal charge. The BSIT operates in an emitter follower configuration so that the magnitude of the signal charge is reflected as a change in the BSIT emitter (36) potential. The BSIT may be made extremely small resulting in a very small floating diffusion capacitance, high responsivity and low noise characteristics.</p> |
