In a direct conversion receiver for mobile communication, it is important to reduce power dissipation. Because a low pass filter in a direct conversion receiver must suppress adjacent channel signals, a high order and high power dissipation is often required in the low pass filter. We propose a new phase compensation technique suitable for a low power transconductor used in a GmC filter as a low pass filter. The new phase compensation technique reduces 10% of power dissipation.
