Abstract: Various embodiments provide a direct current (DC)-DC converter circuit. The DC-DC converter circuit includes a control circuit to switch the DC-DC converter circuit between a charge state, a discharge state, and a tri-state mode. As part of a first control loop, the control circuit may switch the DC-DC converter between the charge state and the discharge state based on the output voltage to provide the output voltage with the target voltage level. Additionally, as part of a second control loop, the control circuit may switch the DC-DC converter between the charge state and the discharge state based on the current through an inductor of the DC-DC converter. The second control loop may provide overcurrent protection for the DC-DC converter. Other embodiments may be described and claimed.

Abstract: A method for pipelining an analog-to-digital conversion of an analog input signal into an N-bit digital output signal is disclosed where a multiplexer is used for the selection of pre-processed digital approximation values from a plurality of adders and subtractors. The selection is set after the decoding of the selected digital approximation values. Thus, considerable more time of the total iteration cycle is available for the pre-amplifier to settle at very high operation frequencies.
