Circuit and method for bandwidth measurement
A circuit for measuring a bandwidth of an amplifier includes first and second capacitors, first through third switches, and a pulse generator. First terminals of the capacitors are coupled to an amplifier input, and a second terminal of the second capacitor is coupled to an amplifier output. The first switch has a control terminal and terminals coupled to a first input node and a second terminal of the first capacitor. The second switch has a control terminal and terminals coupled to the amplifier input and output. The third switch has a control terminal, a first terminal, and a second terminal coupled to the second terminal of the first capacitor. The pulse generator has a first output coupled to the control terminal of the third switch, and is configured to vary a pulse width of a pulse signal supplied from the first output to the control terminal of the third switch.
