Ultra low-power regulator for biomedical implant
Voltage regulators supply a steady voltage supply with low output resistance, given a voltage reference (with high output resistance) and an unreliable/unsteady voltage supply (with low output resistance). A problem of (kinear) regulators is that they are wasting quite a bit of power. The alternative are switching regulators, but those do often require a clock signal.
Both designs are not optimal for our target application: a wirelessly powered micro-implant. the loss of a linear regulator is highly unfortunate, but there is no power during the startup phase of the wireless power transmission to supply a clock of any sorts.
Thus, this project shall investigate compromises of classical approaches or novel designs for regulators / power amplifiers with ultra low standby consumption and low slew rate to minimize ripple in the regulated power supply of a blood sugar implant
