Title: Constant-current source circuit
Inventor: NAKAJIMA SHOTA
IPC: G05F3/16
Filed: 1987-06-23
Abstract: PURPOSE:To obtain a uniform constant-current source by decreasing an error of a base - emitter voltage of a transistor TR of each stage in a constant- current source circuit. CONSTITUTION:An equal current flows to diodes 501-500+(n), respectively, and when it is denoted by Id, it can be derived by an expression I. When each resistance value of resistances 101-100+(n), and each resistance of resistances 401-400+(n) are denoted by R1 and R4, respectively, and when a voltage applied to a diode of the x-th stage is denoted by Vdx, it is derived by an expression II. Also, from the expression I, Vdx=kT/qlnId/Is is obtained, therefore, an expression III is obtained by putting it in the expression II. When the resistance value R1, and each resistance value R2, R3 of resistances 209-200+(n) and 301-300+(n), respectively are set to constant values, Id is determined by R4. Accordingly, a value of Id by which a variation of a shift of a base and an emitter to a variation extending from '1' to (n) of the number of stages (x) becomes the smallest can be derived from determining a value of R4. In such a way, with respect to each stage TR, uniform VBE is obtained and a constant- current source of high accuracy is obtained.
