Abstract:
A voltage switch comprising: a first cascode connected transistor having a gate coupled to a first voltage potential, a source coupled to an input node for the voltage switch, and having a drain; a second cascode connected transistor having a gate coupled to the first voltage potential, a source coupled to receive a complement of a signal received at the input node for the voltage switch, and having a drain; a third cascode connected transistor having a drain coupled to the drain of the first cascode transistor, a gate coupled to a second voltage potential, and having a source; a fourth cascode connected transistor having a drain coupled to the drain of the second cascode transistor, a gate coupled to the second voltage potential, and having a source; a first transistor having a drain coupled to the source of the third cascode transistor, a source coupled to a third voltage potential which is greater than the first and second voltage potentials, and having a gate; a second transistor having a drain coupled to the source of the fourth cascode transistor and to the gate of the first transistor, a source coupled to the third voltage potential, and a gate coupled to the drain of the first transistor; a third transistor having a drain coupled to an output node for the voltage switch, a source coupled to the second voltage potential, and a gate coupled to the drain of the first transistor; and a fourth transistor having a source coupled to the output node for the voltage switch, a gate coupled to the drain of the second cascode, and a drain coupled to the first voltage potential.
