| 20080315950 | Integrated Circuit Amplifiers Having Switch Circuits Therein that Provide Reduced 1/f Noise - Integrated circuit devices include a pair of field effect transistors having shared source terminals, shared drain terminals and shared gate terminals, which may be treated herein as being electrically coupled in parallel. A switch circuit is also provided, which is configured to drive a body terminal of a first one of the pair of field effect transistors with an alternating sequence of first and second unequal body voltages. This alternating sequence is synchronized with a first clock signal. The switch circuit is also configured to drive a body terminal of a second one of the pair of field effect transistors with an alternating sequence of third and fourth unequal body voltages, which is synchronized with a second clock signal. The first and third body voltages may have equivalent magnitudes and the second and fourth body voltages may have equivalent magnitudes. The first and second clock signals may have 50% duty cycles and may be 180 degrees out-of-phase relative to each other. | 12-25-2008 |
