Filed: 1995-12-18
Abstract: PROBLEM TO BE SOLVED: To effectively eliminate switching noise with a small space factor of a chip by applying a signal inverted to a gate drive signal whose level between an input signal level and a GND level to a back gate of a main switch. SOLUTION: A gate drive circuit 6 uses a drive signal C to drive a gate G 101 of a main switch 1 being an nMOS transistor(TR) at a voltage between a voltage VK and a voltage VIN (VK>VIN). Furthermore, a back gate(BG) drive circuit 7 drives a BG 104 at a voltage between the voltage VIN and a GND level (VIN>GND) inversely to the voltage of the gate G101 so as to switch on/off the switch 1. The BG 104 is electrostatically coupled with a source 103 and a drain 102 via a junction capacitance and with a channel via a depletion layer at channel generation so as to cancel a level change in the source 103 and the channel. Thus, switching noise is effectively eliminated with a small chip space factor.

Abstract: PROBLEM TO BE SOLVED: To reduce interface resistance between an electrode and an electrolyte and provide an excellent rate characteristic by coating a collector with an electrode mix that is made by mixing an electrode active material with a mixed solution of a monomer and an electrolytic solution and polymerizing it with a monomer after smoothing it with vibration. SOLUTION: A mixed solution of a monomer that is a precursor of a polymer to function as an electrolytic solution and a binder and an electrolytic solution is mixed with a positive electrode active material and a negative electrode active material. This electrode mix is applied to a collector and thereafter vibration or bending and stretching are given to it. The abundance ratio of the polymer to the positive electrode active material and the negative electrode active material is made to become continuously larger as the location comes closer to the electrode surface side, and the electrode surface is smoothed. Then it is polymerized with a monomer by means of irradiation of radioactive rays such as ultraviolet, electron or gamma rays, so that a solvent--insoluble polymer electrolyte is formed.  Polyethylene oxide that has an averagemolecular weight of 200-1000 and of which end is changed into acrylate can be used for the monomer.
