Abstract: Systems, methods, and apparatuses that may be employed to generate multiple, regulated, isolated power supply voltages are disclosed. In a first implementation, a system includes a circuit configured to supply a plurality of regulated supply voltages. The circuit may include a voltage regulator that can include a first transistor, where the first transistor can be configured to supply a first regulated supply voltage. The circuit may further include a second transistor, operably coupled to the first transistor, where the second transistor can be configured to supply a second regulated supply voltage.

Abstract: Systems, methods, and apparatuses for measuring current flow in an electrochemical cell are disclosed. A system includes a circuit configured to output a mirrored value of an electrical current flowing through an electrochemical cell. The system may also include a voltage controller, coupled to one or more electrodes of the electrochemical cell, for controlling the voltage difference between at least two electrodes of the electrochemical cell. The system may further include a current replication circuit coupled to the voltage controller or the electrochemical cell. The current replication circuit generates a mirrored current of the electrical current flowing in the electrochemical cell. The replicated current may be measured or processed with different circuits and methods to output the current flowing through the electrochemical cell.
