Abstract: A voltage regulator has an input node and an output node, a supply voltage rail, and an output transistor (Mn1) with its drain connected directly to the supply voltage (Vdd) rail and its source connected to the output node (14). A first differential voltage amplifier (A1) with its output (11) is coupled to the gate of the output transistor (Mn1). A control loop and a sense transistor (Mn2) are connected to the output transistor and to behave as a scaled copy of the output transistor in which the output transistor acts as a voltage follower, and in which the drain of the sense transistor is connected to the control loop.

Abstract: A processor system includes first and second regulators for regulating an adjusted supply voltage. The first and second regulators generate a plurality of control signals to regulate an adjusted power supply voltage and that generate a charge when a droop level falls below a droop threshold value by implementing first and second control loops. A supply adjustment block with the two regulators and control loops are provided for each processor core allowing different cores to have different regulated supply levels all based on one common supply. One regulator is a global regulator while another is a local regulator found in each of the processing tiles. Processing tiles are grouped into two groups wherein one group includes tiles that may powered down to save power. Voltage rails of the two groups are selectively connected to equalize voltage levels when both groups are powered on and operating.

Abstract: A low standby power DC-DC converter can be powered down during standby mode. The DC-DC converter can be periodically awakened between sleep cycles to check if the output voltage needs to be recharged (refreshed). The duration of the sleep cycles can be varied to accommodate for changing load conditions that would affect the output voltage.

Abstract: A floating core network for secure isolation of a circuit from an external supply interface is described. Isolation of a core is accomplished through a dynamic current limiting network providing an isolated core voltage to the core; and an isolated supply for the corresponding core that is continuously recharged by the dynamic current limiting network. The dynamic current limiting network can include two control loops, one control loop providing a fixed gate voltage to a p-type transistor supplying current to the isolated supply and another control loop providing a fixed gate voltage to an n-type transistor sinking current from the isolated supply.

Abstract: This disclosure relates to radio frequency (RF) power converters and methods of operating the same. In one embodiment, an RF power converter includes an RF switching converter, a low-drop out (LDO) regulation circuit, and an RF filter. The RF filter is coupled to receive a pulsed output voltage from the RF switching converter and a supply voltage from the LDO regulation circuit. The RF filter is operable to alternate between a first RF filter topology and a second RF filter topology. In the first RF filter topology, the RF filter is configured to convert the pulsed output voltage from a switching circuit into the supply voltage. The RF filter in the second RF filter topology is configured to filter the supply voltage from the LDO regulation circuit to reduce a ripple variation in a supply voltage level of the supply voltage. As such, the RF filter provides greater versatility.

Abstract: The invention describes a process for symmetrical load distribution in power supply units connected in parallel on the output side. The invention makes it possible without expensive means for at least two or more power supply units of which the voltage outputs are connected in parallel look at a reference voltage and take equal parts in supplying power to the common user via their regulating device dependently upon the output voltage and the reference voltage. This is achieved according to the invention that the outputs (MP1, MP2 to MPn) of the reference voltage sources (UQ1, UQ2 to UQn) of all the power supply units in parallel in the arrangement (SPV1, SPV2 to SPVn) are all taken to a shared reference bus (RB) via a decoupling device (REK1, REK2 to REKn).

Abstract: The invention concerns an electrical switching circuit with a plurality of current voltage transformers. The transfer resistance of a current voltage transformer is strongly temperature-dependent, particularly in integrated circuits. In order to suppress the drift of the transfer resistance in a plurality of current voltage transformers (Wr, W1, ..., Wn), one of the current voltage transformers is a reference current voltage transformer (Wr), the transfer resistance of which is compared with a reference resistance (Rref). The result is used to derive a criterion for adjusting the transfer resistance of all current voltage transformers (Wr, W1, ..., Wn). Application to integrated circuits with a plurality of current voltage transformers.
