    摘要: The analog electronic watch includes: a crystal oscillator; an oscillator circuit; a frequency divider circuit; an output control circuit; a constant voltage circuit; and a cell. The constant voltage circuit and the output control circuit are powered from the cell. The oscillator circuit and the frequency divider circuit are powered from the constant voltage circuit. The constant voltage circuit is capable of outputting a first constant voltage and a second constant voltage in a switchable manner. The second constant voltage is a voltage which is equal to or lower than a cell voltage. The first constant voltage is a voltage which is smaller than the second constant voltage. The constant voltage is switched to the second constant voltage in a period of outputting the motor drive pulse.

    摘要: A voltage multiplier for an electronic time-measuring apparatus comprising cells, each of which including two capacitors, a pair of complementary field-effect transistors (FET'S) acting as switches, and an inverter comprising a pair of FET'S. The elements of the cells are such that they are capable of being integrated together with the rest of the circuit of the time-measuring apparatus.The voltage to be increased is fed via a first capacitor to the first pair of FETS'S and at the same time to the input of the inverter whose output drives with the correct phase the first pair of FETS'S, which alternatively switches the input signal to a common point of the cell and to an output terminal of the cell, thus charging a second capacitor with the opposite polarity than that of the input signal respective to the common point of the cell. In order for the input voltage to be further increased, the cells can be cascaded in a chain, the common point of one cell being connected to the output terminal of the preceding cell. Each cell will add to the preceding one an amount of voltage equal to that of the input voltage.

    摘要: In the transition from a state in which charge is being transferred from a large-capacitance secondary power supply to an auxiliary capacitor through a step-up/down circuit by a step-up/down multiplying factor M′ (M′ is a positive real number excluding one) to a state in which the large-capacitance secondary power supply and the auxiliary capacitor are electrically directly coupled, the electrical energy is transferred from the large-capacitance secondary power supply to the auxiliary capacitor through the step-up/down circuit by a step-up/down multiplying factor M=1 in a non-stepping-up/down state. A potential difference between the large-capacitance secondary power supply and the auxiliary capacitor is less than a predetermined potential difference. Since a sudden variation in a power supply voltage due to changing the step-up/down multiplying factor is prevented, malfunctioning in an electronic apparatus resulting from the sudden variation in the power supply voltage is prevented.

    摘要: A D.C. potential multiplier has a first capacitor which is time shared between two potential multiplying circuits. In the first multiplying circuit, gates connect the first capacitor for charging from a potential source. The gates then switch the capacitor into potential adding series with the source for charging a second capacitor toward the combined potential of the source and first capacitor. The gates next switch the first capacitor into the second multiplying circuit for charging the first capacitor from the second. The gates then switch the first and second capacitor into potential adding series for providing an output potential from the second potential multiplying circuit.

    摘要: A cascaded charge pump based power supply for use with low voltage dynamic random access memory (DRAM) includes a charge pump and a non-overlapping clock signal generator. The charge pump circuit has two pump cascades coupled in parallel. Each pump cascade includes a plurality of pump stages connected serially between a power supply voltage and an output supply node. Adjacent stages of each cascade are clocked on opposite phases of the system clock signal. The charge pump drives an output supply node on both the rising and falling edge of the system clock signal. A non-overlapping clock signal generator for use with a charge pump has a charge sharing transistor which equalizes the non-overlapping output clock signals through charge sharing during the non-overlap period between subsequent phases of the system clock. The charge pump and capacitors are implemented using p-channel devices and the first stage of each cascade is constructed using thin-oxide devices.

    摘要: Energy is conserved and the life of a lithium battery is extended in a timepiece by using a voltage reduction circuit for normal operation and a voltage regulating circuit during periods of heavy current drain, e.g., alarm or lamp function. A no-clock detector indicates the functional status of the timekeeping standard signal generator and voltage is raised to enable self-starting when oscillator signals are absent. A timer holds the regulated voltage on-line until operations stabilize after a period of heavy load and capacitors used in the voltage reduction circuit bolster the regulated voltage output during high load periods.

    摘要: A booster circuit for use in a miniaturized battery operated electronic instrument such as an electronic wristwatch is provided. The booster circuit includes a first capacitor and a second capacitor. A switching circuit is adapted to be disposed in a first operative mode and thereby apply a supply voltage produced by a battery to a first capacitor and thereby charge same to a first voltage. The switching circuit is further adapted to be disposed in a second operative mode to apply the supply voltage and the first voltage stored in the first capacitor in the second capacitor to produce a predetermined output voltage for driving a load substantially equal to the sum of the supply voltage and the first voltage stored in the first capacitor. The booster circuit is characterized by a load detector for producing a load detection signal in response to a change in the load driven by the output voltage. Additionally, an impedance control circuit is coupled to the switching circuit for controlling the impedance of the switching circuit in response to the load detection signal being applied thereto so that the current consumed by the booster circuit is varied in response to the load detection signal.
