HIGH-SPEED CURRENT COMPARATOR SUITABLE FOR NANO-POWER CIRCUIT DESIGN

摘要

Systems and methods according to one or more embodiments are provided for a current comparator with biasing circuitry to provide for low power consumption and high-speed performance. In one example, a system includes an input port to receive a current pulse and an amplifier configured to provide a voltage pulse at an output port in response to the current pulse. The system also includes a first biasing circuit coupled between the output port and the input port to selectively limit a voltage at the input port. The system further includes a second biasing circuit coupled to the amplifier to selectively adjust a bias of the amplifier.
