Zusammenfassung:	A microfluidic pump having a firing mechanism for ejecting fluid out of a firing chamber during a firing sequence, which includes a firing step followed by a wait step. A power circuit activates and deactivates the firing mechanism in response to a control signal, which controls the timing of each step and is provided by a logic circuit. The control signal controls the firing step and is dependent on a predetermined fixed frequency signal provided by a first oscillator. The control signal controls the wait step and is dependent on a variable frequency signal provided by a second oscillator. A first input provides a variable input signal to the second oscillator. The second oscillator varies the variable frequency signal according to the variable input signal. The logic circuit also varies the control signal based on the variable frequency signal to vary the length of the wait step.
