The circuit 150 includes a first circuit portion 151 and can further include a second circuit portion 161 that is mutually exclusive from the first circuit portion 151. The first circuit portion 151 includes a first sub-portion 152 and a second sub-portion 153. The second circuit portion 161 includes a first sub-portion 162 and a second sub-portion 163. The first sub-portion 152 of the first circuit portion 151, the second sub-portion 153 of the first circuit portion 151, the first sub-portion 162 of the second circuit portion 161, and the second sub-portion 163 of the second circuit portion 161 can each be configured to perform a circuit function that operate best under a different set of power characteristics. For example the first sub-portion 152 of the first circuit portion can be configured to perform a set of power management procedures using a power with 50 kHz frequency and 20 Volts potential, while the second sub-portion 163 of the second circuit portion 161 can be configured to perform a set of signal communication procedures using a power with 100 kHz frequency and 200 Volts potential.
