Title: Drive circuit for static induction transistor
Inventor: SUZUKI BUNKICHI
IPC: H03F3/16
Filed: 1986-04-30
Abstract: PURPOSE:To apply a sufficient positive gate voltage to reduce an on-resistance at the conduction of an SIT by connecting at least a DC bias supply circuit, a diode and a specific series circuit between a gate and source of a static induction transistor (TR). CONSTITUTION:A capacitor C is charged by a current i1 via a diode D2 and an internal resistor R3 at a period of 0-T1(sec) for positive drive and the capacitor C is discharged at a rate of current i2 via a diode D1 and a resistor R1 for a negative drive period T1-T2(sec). The charge/discharge is repeated to a periodic drive signal Ep and an optimum operation bias voltage is obtained at the steady-state. In order to hold the SIT at the cut-off state, a resistor R2 is connected in parallel with the diode D1 and a negative voltage-Ec is fed to a gate G via the resistors R2, R1. Thus, the variation in the input characteristic of the SIT and of the drive pulse is to be followed, the optimum bias to the SIT is applied and teh drain-source and gate-source permissible maximum reverse dielectric strength of the SIT is utilized.

Filed: 1988-04-22
Abstract: PURPOSE:To transmit transmission data to the reception side without buffering to shorten the transmission time by providing each node with a selector for connection to another node and using a center controller to control switching of this selector. CONSTITUTION:For example, in case of data transfer from a node 2 to a node 4, the node 2 transmits data, which indicates that the node 2 has data to be transmitted to the node 4, to a controller 1. The controller 1 analyzes this data, and the controller 1 transmits a data transmission instruction to the node 2 when transmission to and reception from the node 4 is possible. Thereafter, a control processing part 11 of the controller 1 controls a multiplexer of the selector of the node 4 to open the input of the node 2. Thus, data transmitted from the node 2 is transmitted to the node 4 through the controller 1.
