Title: Current mirror
Inventor: UEDA SEIICHI
IPC: H03F3/343
Filed: 1983-11-11
Abstract: PURPOSE:To attain current mirror operation with excellent frequency characteristic by providing a signal transmission circuit comprising a differential amplifier and an emitter follower or the like between the input circuit and the output circuit of a current mirror circuit consisting of an L-PNP transistor (TR). CONSTITUTION:An input signal Vin is fed to a base of a TRQ11 via a terminal No.1. The input current Iin proportional to the input signal Vin flows to the L- PNP TRQ12 and the TRQ11 from a current +Vcc fed to a terminal No.2. A voltage VBEQ12 proportional to the Iin is produced across the Q12 as a load and a voltage +Vcc-VBEQ12 is applied to a non-inverting input terminal (+) of an operational amplifier 1 as a signal transmission circuit of high input impedance. On the other hand, since an output signal of the operational amplifier 1 is fed back negatively by 100% to the inverting input terminal, the operational amplifier 1 acts like a low output impedance voltage follower having the voltage gain 1. The provision of the said operational amplifier 1 prevents an AC impedance of the TRQ12 from giving effect on the base circuit of the TRQ12.
