An adiabatic pal-2n jk flip-flop based on finfet device

ActiveCN105978534BEasy to chargeEasy to recycleElectric pulse generatorEngineeringPower–delay product
The invention discloses an adiabatic PAL-2N structure type JK flip-flop based on Fin-FET devices, comprising a first P-type Fin-FET, a second P-type Fin-FET, a third P-type Fin-FET, a fourth P-type Fin-FET, a first N-type Fin-FET, a second N-type Fin-FET, a third N-type Fin-FET, a fourth N-type Fin-FET, a fifth N-type Fin-FET, a sixth N-type Fin-FET, a seventh N-type Fin-FET, an eighth N-type Fin-FET, a ninth N-type Fin-FET, a tenth N-type Fin-FET and an eleventh N-type Fin-FET. The advantage is that under the condition that the circuit performance of the adiabatic PAL-2N structure type JK flip-flop is not affected, the number of Fin-FETs is reduced, the circuit area is reduced significantly, and the time delay, power consumption and power-delay product are reduced significantly.

Power-supplying circuit

InactiveCN103095115AEliminate Static Power ConsumptionSave electricityBatteries circuit arrangementsEfficient power electronics conversionEngineeringControl unit
The invention provides a power-supplying circuit which comprises a switch unit, an energy conversion unit, a detection unit, a control unit and an output end. The switch unit is connected between an external power supply and the energy conversion unit, the energy conversion unit converts the external power supply into an input a load needs and outputs the input through an output end, the detection unit is connected between the energy conversion unit and the output end in series, and the detection unit detects the output current of the output end. The control unit is connected between the detection unit and the switch unit. When the detection unit detects that no current is outputted from the output end or current is very small, the control unit enables the switch unit to be cut off according to the detection signals provided by the detection unit.

A low-power binary-search ADC system based on full dynamic structure

ActiveCN112422130BLower Offset VoltageReduce power consumptionAnalogue/digital conversionElectric signal transmission systemsCapacitanceHemt circuits
The present invention claims to protect a low-power Binary-Search ADC system based on a full dynamic structure, which includes a bootstrap sampling circuit, a full dynamic comparator array with a preamplifier and a decoder array, wherein the bootstrap sampling circuit includes a charge pump circuit, bootstrap sampling switch and sampling capacitor; decision array includes dynamic preamplifier, dynamic comparator and back end decoder array for each stage. The purpose of the present invention is to improve all the main modules in the circuit into a dynamic structure, when there is no control timing input, the circuit does not work, and most of the timing signals for the control circuit operation are generated by the circuit structure itself, so that the power consumption can be further improved. reduce. The innovation is that compared with the traditional structure, the present invention has a significant effect on reducing the power consumption of the circuit based on the full dynamic structure. The full dynamic structure of the present invention can not only reduce the power consumption of the circuit, but also reduce the influence of the offset voltage of the circuit by the dynamic amplifier and ensure the accuracy.
