Patent ID: 8143934

Claim:
A system comprising: a first voltage pump to generate a first pump voltage from an analog voltage supply signal, wherein the first pump voltage is configured to provide a continuously different value than the analog voltage supply signal; and a second voltage pump to generate a second pump voltage from the same analog voltage supply signal; and a switching pad to receive an analog input signal from an external source and route the analog input signal to analog processing circuitry over one or more analog signal busses based on the first pump voltage and the analog voltage supply signal, wherein the switching pad is configured to route the analog input signal to the analog processing circuitry over a first analog signal bus of the one or more analog signal busses based on the first pump voltage or a second analog signal bus of the one or more analog signal busses based on the second pump voltage, wherein the switching pad includes a first switch circuit comprising a transistor where a gate terminal of the transistor is controlled by the first pump voltage to route the analog input signal onto the first analog signal bus, and includes a second switch circuit controlled by the second pump voltage to route the analog input signal onto the second analog signal bus based on the second pump voltage, and wherein at least one of the first switch circuit and the second switch circuit comprises a field-effect transistor (FET) based T-switch having a first switch to receive the analog input signal and a second switch to output the analog input signal to the first analog signal bus or the second analog signal bus.
