Abstract: A skin biopsy device and a method of operating a skin biopsy device are disclosed. The skin biopsy device comprises a base member configured to be placed onto a skin surface; an cutting member configured to be received by the base member and to be movable relative to the base member in a direction substantially orthogonal to the skin surface; and an actuation member configured to drive the cutting member to travel a predetermined distance at a predetermined velocity in said direction.

Abstract: A charge pump for a phase-locked loop (PLL) has accurate matching of charge and discharge currents applied to the PLL's loop filter. A variable current-sink transistor has its gate-to-source voltage adjusted to match a source current from a fixed current source. An intermediate node in-between series transistors between the current source and sink is sampled by a sampling transistor that connects the intermediate node to a sampling capacitor. The sampling capacitor's voltage is the gate-to-source voltage of the variable current-sink transistor. The variable current-sink transistor has its gate and drain coupled together through the sampling transistor during calibration periods when the charge pump is otherwise idle. When the source current exactly matches the sink current, the gate-to-source voltage stored on the sampling capacitor reaches steady state. Up and down currents are balanced in driver transistors that match the series transistors.
