Title: A/d converter and receiver using the same
Inventor: NAKAGAWA SHIGEO
IPC: H03M1/36
Filed: 2006-09-14
Abstract: <P>PROBLEM TO BE SOLVED: To make a sample/hold circuit and a comparator constituting an A/D converter low power consumption.  <P>SOLUTION: In the sample/hold circuit SHC of a first stage, connection nodes of two capacitors C2 and C3 are connected to an operation potential which is substantially stably maintained through a switch SW8 during a sample mode. During the sample mode, it is possible to accurately sample an analog input signal Vin to the capacitor C2 and input offset voltage of an operational amplifier OPA to the capacitor C3 so that low power consumption and high performance can be achieved during the sample mode. By control by a bias control circuit BCC, a preamplifier AMP of a comparator COP of the post stage performs amplification with a large amplification rate when differential voltage of differential input signals Vsig and Vref supplied from outputs of the sample/hold circuit SHC of the first stage is small, and performs amplification at a small amplification rate when the differential voltage is sufficiently large. The acceleration and low power consumption of the comparator COP of the post stage can be achieved.  <P>COPYRIGHT: (C)2008,JPO&INPIT
