Filed: 1990-09-19
Abstract: PURPOSE:To eliminate a bridge at the time of melting adjacent cream solder layer by noncontinuously providing cream solder layers longitudinally on rectangular lands aligned in a substantially parallel proximity state. CONSTITUTION:Rectangular lands 2 to be connected with leads of an electronic component are provided at a predetermined pitch on a board 1.

IPC: H03K5/13
Filed: 1990-09-25
Abstract: PURPOSE:To make it possible to prepare an active load type source ground inverse amplifying circuit superior in dynamic range, frequency band, and so on by controlling the voltage at gate electrodes with the use of a control signal of low output impedance that is nearly in proportion to the voltage between the drain and source of an active load type MOS transistor and that is level-shifted by a predetermined voltage. CONSTITUTION:MOS transistor Q9 and constant current circuit I1 altogether constitute a levelshift circuit of drain ground type that power-amplifies an output signal V0 which is generated at contact point P and that supplies the gate electrodes of MOS transistor Q8 with the amplified output signal, while in the MOS transistor Q8 the gate electrodes are not in contact with the source contact point, and the bias power between the gate and the source is controlled by a signal VX. If the amplitude of an input signal VC deviates to the side of voltage Vcc, the gate electrode voltage of MOS transistor Q8 drops and is maintained at the forward bias. On the other hand, if the amplitude of input signal VG deviates to the side of voltage VEE, since although the gate electrode voltage of MOS transistor Q8 rises, a signal VX is levelshifted as much as voltage VGS obtained between the gate and source of MOS transistor Q9, the gate electrode voltage is always low, thus causing no pinchoff.
