Claim 0:
1. An apparatus, comprising
an array of symmetric receiver switches coupled between a receiving apparatus and an array of ultrasonic transducers,
wherein:
a first symmetric receiver switch of the array of symmetric receiver switches is comprised of
a first transistor having a first gate, a first source, a first body, and a first drain, and
a second transistor having a second gate, a second source, a second body, and a second drain,
with the first and second gates coupled to each other, and
with the first and second sources coupled to each other to a drain of a source transistor, and
with the first and second bodies coupled to each other and to a drain of a body transistor,
with an electric potential of the first and second sources and an electric potential of the first and second bodies independently configurable by the body and source transistors,

the first drain is connected to a first ultrasonic transducer of the array of ultrasonic transducers,
the second drain is connected to the receiving apparatus,
during a pulse transmission (TX) mode of the apparatus, the body transistor and the source transistor are on to set the first and second gates, the first and second sources, and the first and second bodies at a same electric potential, and,
during a reception (RX) mode of the apparatus, at least the body transistor is configured such that:
the first and second gates are at a first floating electric potential, or
the first and second bodies are at the first floating electric potential, or
the first and second gates and the first and second bodies are at the first floating electric potential.
