| 摘要 |
The current invention relates, inter alia, to charge pulse amplitude and time detecting circuits, offering very low amplitude and temporal noise, and overcoming noise performance limits in charge pulse detection circuits according to prior art. Embodiments of the present invention may include a sensing device delivering charge pulses onto a sense node, an active buffer buffering the voltage on the sense node with a low impedance, a recharge device removing signal charge from the sense node, a noise filter connected to the output of the active buffer transmitting signal voltage pulses while attenuating noise from the recharge device. Additional and alternative embodiments are specified and claimed. |
