DIGITAL TUNING CIRCUIT OF Gm-C FILTER

摘要

The invention Gm ( transconductance ) -C ( capacitor) relates to the tuning of the filter circuit , a capacitor during the tuning mode, but the clock signal is used , gm during tuning mode without using the clock signal the capacitor variation ( deviation) of the reflected current (DC) value may be tuned by using a Gm, accordingly , a reception signal according to the clock signal can prevent the deterioration .
