DUAL VOLTAGE SWITCH WITH PROGRAMMABLE ASYMMETRIC TRANSFER RATE

A dual voltage switch enables the generation of a pulse which toggles between user-provided first and second voltages (V1 and V2), for which the positive and/or negative slew rates are programmable by means of a user-provided capacitance. A first switch conducts a current I1 between V1 and a common output node in response to a first control voltage, and a second switch conducts a current I2 between V2 and 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 V1 at a transfer rate of I1/C when the first control voltage is provided, and pulled down to V2 at a transfer rate of −I2/C when the second control voltage is provided.
