Abstract: A level control circuit uses a reference voltage generated from a mains voltage signal by a reference circuit to provide a feedforward control signal. This control signal is used to generate a control signal for controlling a switched mode power converter. The reference circuit comprises a combining circuit adapted to apply a pulse width modulation control signal indicative of said level such that said reference voltage contains the level information. In an embodiment, the reference circuit comprises a voltage divider comprising a resistor circuit and the combining circuit comprises an adjustment module to which a pulse width modulation control signal is applied thereby to change the effective voltage divider ratio to implement level control. The level control further comprises a buffering capacitor or a buffered low pass filter coupled to the output (SET) of the voltage divider. This provides a power factor correction approach for active level control, and which can be implemented very simply and with low cost. It can be used for controlling lighting dimming.

Abstract: A bit cell circuit of a most-significant bit (MSB) of a multi-bit product generated in an array of bit cells in a compute-in-memory (CIM) array circuit is configured to receive a higher supply voltage than a supply voltage provided to a bit cell circuit of another bit cell corresponding to another bit of the multi-bit product. A bit cell circuit receiving a higher supply voltage increases a voltage difference between increments of an accumulated voltage, which can increase accuracy of an analog-to-digital converter determining a pop-count. A bit cell circuit of the MSB in the CIM array circuit receives the higher supply voltage to increase accuracy of the MSB which increases accuracy of the CIM array circuit output. A capacitance of a capacitor in the bit cell circuit of the MSB is smaller to avoid an increase in energy consumption due to the higher voltage.

Abstract: Techniques are provided to implement hardware accelerated computing of eigenpairs of a matrix. For example, a system includes a processor, and a resistive processing unit coupled to the processor. The resistive processing unit includes an array of cells which include respective resistive devices, wherein at least a portion of the resistive devices are tunable to encode values of a given matrix which is storable in the array of cells. When the given matrix is stored in the array of cells, the processor is configured to determine an eigenvector of the stored matrix by executing a process which includes performing analog matrix-vector multiplication operations on the stored matrix to converge an initial vector to an estimate of the eigenvector of the stored matrix.

Abstract: A multiplier has a MOSFET in a common source configuration. A MOSFET current source is coupled to a drain terminal of the MOSFET. An inverter has an input coupled to the drain terminal of the MOSFET. An output of the inverter gates two currents whose current magnitudes are proportional. A first capacitor has a first terminal coupled to a first of the two currents and a gate of the MOSFET and a second terminal grounded. A second capacitor has a first terminal coupled to a second of the two currents and a second terminal coupled to the first of the two currents. The multiplier is first reset by discharging a gate capacitance of the MOSFET. In a next reset phase, the second capacitor holds a multiplied value of charge.

Abstract: The invention relates to a multiplier circuit comprising a multiplier core that contains two cross-coupled transistor pairs (2, 3; 4, 5). According to the invention, a first and a second signal source (10, 11, 13, 14), which are controlled by a first or second signal that is to be multiplied, are respectively connected to control inputs of the transistors (2 to 5) of the multiplier core for inverting the current between the transistor pairs (2, 3; 4, 5), or in a differentiating manner between the transistors (2, 4; 3, 5) of the differential amplifiers. The high degree of symmetry that can be achieved for the input gates of the circuit permits a particularly precise multiplication with excellent linearity. The inventive multiplier can be used, for example, as a high-frequency mixer circuit or as a 90 DEG phase-detector circuit.
