Title: Low voltage pll semiconductor device
Inventor: YAGASHIRA SHOICHI
IPC: H03L7/08
Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To suppress a leak current at the time of standby and to reduce power consumption by providing a substrate bias circuit having a switch element for switching power sources to be used in operation and standby. SOLUTION: The frequency of a compare signal fin inputted to a substrate bias circuit 2 is divided by a prescaler circuit 5 and afterwards, this signal is inputted to a frequency divider circuit 6 together with a reference signal OSCin. A phase comparator circuit 7 compares the phases of both the signals outputted from the frequency divider circuit 6 and corresponding to the difference of phases, an output signal is supplied to a charge pump circuit 8. Besides, a power save signal PS is inputted to the bias circuit 2 and power sources VDD and VP are switched. At the time of standby, the bias circuit 2 selects the power source VP so that a substrate bias voltage can be increased in the state of turning off MOS transistors consisting of the prescaler circuit 5, frequency divider circuit 6 and phase comparator circuit 7.

Title: Laser diode driving circuit
Inventor: SUZUKI FUMIO
IPC: H01S5/042
Filed: 1991-02-08
Abstract: PURPOSE:To minimize the power consumption by keeping the voltage amplitude of an input signal constant and equalizing the voltage of the lower voltage side of the signal to that of a constant voltage source. CONSTITUTION:Transistors TRs 5 to 7 and 2, a constant voltage source 14, and a resistor 9 constitute a constant current source. In this case, sizes of TRs 7 and 2 are equalized to equalize current values flowing to collectors of TRs 7 and 2. The pulse signal inputted to an input terminal 16 drives a resistor 11. The pulse signal applied to the resistor 11 drives a laser diode 12 through a TR 4 by a current. When the input signal voltage is equal to the voltage of the constant voltage source 14, the voltage applied to the resistor 11 is '0'V and the diode 12 is not driven. Consequently, the voltage on the low potential side of the input pulse signal is equalized to the voltage of the constant voltage source 14 and the voltage on the high potential side is made higher than the voltage of the constant voltage source 14, and thereby, an unnecessary current is not generated when the diode 12 is driven.
