Abstract
A dual voltage switch enables the generation of a pulse which toggles between user-provided first and second voltages (Vand V), for which the positive and/or negative slew rates are programmable by means of a user-provided capacitance. A first switch conducts a current Ibetween Vand a common output node in response to a first control voltage, and a second switch conducts a current Ibetween Vand the common output node in response to a second control voltage. A capacitance C is connected to the common output node. A control circuit alternately provides the first and second control voltages such that the common output node is pulled up to Vat a transfer rate of I/C when the first control voltage is provided, and pulled down to Vat a transfer rate of −I/C when the second control voltage is provided.
