Title: Current switching cell and d/a converter using the same
Inventor: MATSUMOTO MASAAKI
IPC: H03K19/0952
Filed: 1995-12-22
Abstract: PROBLEM TO BE SOLVED: To provide a current switching cell operatable at a low speed with a low voltage power source by changing reference signals to be supplied to the control terminal of a third active element operated in terms of a differential circuit corresponding to the states of first and second active elements. SOLUTION: When the address signals Ybj of one of two inputs impressed to a current switching circuit 1 are 'L', an MOSFET-MP2 is turned on and the current of a current source 2 is made to flow to the MP2. Thus, the current is not made to flow to an MP3 and the state of this current switching cell 6 is turned off. Then, when the signals Ybj are 'H', the MP2 is turned off. At the time, when the other signals Yaj are 'L', the output of a NAND circuit 3 becomes 'H' and an MP1 inside the circuit 1 is turned off. Since the MP1 and the MP2 are turned off, the current of the current source 2 is made to flow to the MP3. Thus, the current is made to flow to a load resistor RL connected to an output terminal and the state of the cell 6 is turned on.
