Patent ID: 8847441

Claim:
A device for producing a current pulse, comprising: a first supply terminal and a second supply terminal configured to provide a power supply voltage between the first and second supply terminals; a first switch situated in a control current branch between the first and second supply terminals, wherein the first switch is configured to switch a control current through the control current branch as a function of an actuation signal; and a current mirror having a control transistor and a signal transistor, wherein the control transistor and the signal transistor each have a first terminal, a second terminal and a control terminal, and wherein the control transistor is situated in series to the first switch in the control current branch, and wherein the signal transistor is configured to make available the current pulse as a function of the control current through the control transistor; wherein the first terminal of the signal transistor is connected via a first resistor to the first supply terminal, and wherein the first terminal of the control transistor is connected via a second resistor to the first supply terminal; and a second switch, a third resistor, a fourth resistor and a fifth resistor, wherein the second terminal of the control transistor is connected to a first terminal of the second switch, a second terminal of the second switch is connected via the fourth resistor to the first terminal of the first switch, a control terminal of the second switch is connected via the third resistor to the first supply terminal and connected via the fifth resistor to the first terminal of the first switch.
