Data

[0085]FIG. 4 is a graph 400 showing a current output of an example wide range current switching circuit in response to a pulse for a range of currents. The y-axis shows the current output (e.g., Iout of FIG. 1) in milliamps. The x-axis shows time in nanoseconds. The curves 402, 404, 406, 408, and 410 indicate the outputs when the input current (e.g., Iin of FIG. 1) of the example wide range current switching circuit is set to different values between about 50 micro-amps and 1 milliamp. The example wide range current switching circuit is configured to switch on and off to provide an output pulse of about 1 nanosecond. The rise and fall times are about 125 picoseconds. [0095] [0096]FIG. 5 is a graph 500 showing the output currents of different current switching circuits designs. The y-axis shows the current output in milliamps. The x-axis shows time in nanoseconds.

Abstract

A wide range differential current switching circuit can operate across a wide range of input currents and across a broad range of frequencies. A first differential current source can include a first transistor and a second transistor. The first transistor receives a switching signal and provides an output current and at output node. The second transistor receives an inverted switching signal, the first transistor and the second transistor coupled to each other at a tail node. A current source provides an input current to the tail node. A third transistor can provide a boost current to the tail node while the first transistor is off.

Description

FIELD[0001]This disclosure relates to current switching circuits and applications thereof.BACKGROUND[0002]A current switching circuit can generate current pulses at an output node. Such a current switching circuit can include a differential pair of transistors. The performance of the differential transistors may change based on the current provided to the differential transistors and / or the switching frequencies of the differential transistors. This can limit the performance of a current switching circuit.SUMMARY OF THE DISCLOSURE[0003]One aspect of this disclosure is a current switching circuit comprising: a differential current switching circuit and a third transistor configured to provide a boost current to the tail node while the first transistor is off. The differential current switching circuit includes: a first transistor configured to receive a switching signal and to provide an output current to an output node; a second transistor configured to receive an inverted switching...
