Abstract

PURPOSE:To reduce the area of an IC and current consumption, and to make the adjustment easy, by controlling a plurality of blocks of and electronic watch through the current information signal obtained from one reference current source. CONSTITUTION:A bias is given to a terminal PIN of a dynamic frequency divider 50 from a reference current source 48 via a resistor 49, and a bias is given to a terminal NIN from the source 48 via a resistor 51. An input signal is supplied from a time reference signal source 46 via capacitors 32, 34. The output of the dynamic frequency divider 50 is transmitted to a static frequency divider 54 via a buffer 52. The output of the static frequency divider 54 is given to a static frequency dividing circuit 58 via a level shifter 56. A motor driver 60 responses to an output signal of the circuit 58 to drive a motor 62, which operates a pointer type display device 64.
