A low-power single chip FM/AM radio IC capable of extending the batter
y life of a radio has been developed. Decreasing the current consumpti
on is realized solely by new circuit design techniques without making
changes to the conventional processes in IC fabrication. Characteristi
cs of this IC is not degraded even though the current consumption is d
ecreased, but instead, operating time has been improved to be four or
five times than that of the conventional radio. [1]
