CROSS-COUPLED CHARGE TRANSFER SENSE AMPLIFIER CIRCUITS Sense amplifiers employing charge-transfer techniques and cross-coupled devices for use with memory cell arrays or as comparators, polarity sensors and differential amplifiers are described which include a unique preamplifier circuit having cross-coupled actuable devices and which provides a cross-coupled charge-transfer feature. The sense amplifier also includes actuable devices which provide further amplification. The preamplifier circuit includes two precharge actuable devices which have their gate electrode. connected to the phase 1 line and which have their source electrode connected through separate capacitors to the phase 2 line. The terminals of the two preamplifier charge-transfer devices which are cross-coupled are also connected at the aforesaid circuit nodes and to the bit/sense lines and to the further amplification devices. The disclosure describes two embodiments of a preamplifier circuit, each of which is shown in combination with a plurality of different further amplification circuits. |
