Abstract:
1. A noise resistant, switch control circuit comprising: a low pass filter configured to couple a low pass output of the low pass filter to a first terminal of a switch, the switch having the first terminal, a second terminal, and a control terminal; a first voltage clamp coupled to the low pass filter, the first voltage clamp configured to couple to the control terminal of the switch and to limit a voltage of the control terminal relative to the first terminal to within a first clamping range; a second voltage clamp coupled to an input terminal of the switch control circuit, the second voltage clamp configured to couple to the control terminal of the switch, the second voltage clamp further configured to reduce a level of a control voltage coupled to the second voltage clamp; and a bias device configured to couple to the control terminal of the switch and to impress a biasing voltage to the control terminal.
