摘要:
A biasing scheme for a voltage-to-time converter (VTC). An example biasing circuit generally includes a reference current source; a feedback loop current source; an amplifier having a first input coupled to a target voltage node, having a second input, and having an output coupled to a control input of the reference current source and to a control input of the feedback loop current source; a first capacitive element; a first switch coupled in parallel with the first capacitive element; a second switch coupled between the feedback loop current source and the first capacitive element; and a third switch coupled between the first capacitive element and the second input of the amplifier.
