Patent number: 6127958Abstract: An analog/digital (A/D) converting circuit is provided that stabilizes system operation, reduces power consumption in an analog circuit region and uses a selected metal-to-metal capacitor, which has a small parasitic capacitance value. The A/D converting circuit includes a first sample/hold amplifier for sampling/holding an analog input signal, a switch for selecting one of a signal outputted from the first sample/hold amplifier and a feedback signal and an A/D sub-converter for converting an analog signal outputted from the switch to a digital signal. A multiplying D/A converting block converts an output signal from the A/D sub-converter to an analog signal and amplifies a difference value obtained between the analog signal and the analog signal outputted from the switch. A second sample/hold amplifier samples/holds a signal outputted from the multiplying D/A converting block and outputs the feedback signal to the switch.Type: GrantFiled: September 10, 1998Date of Patent: October 3, 2000Assignee: Hyundai Electronics Industries Co., Ltd.Inventors: Dong-Young Chang, Jae-Yup Lee, Seung-Hoon Lee, Yong-In Park, Seung Woo Park

Patent number: 6052025Abstract: Operational amplifier integrated circuits include a differential input stage, a cascode current mirror, a cascode current source and a preferred bias signal generator which is responsive to a clock signal and is electrically coupled to the differential input stage, the cascode current mirror and the cascode current source. This preferred bias signal generator sequentially enables the cascode current mirror and then the differential input stage in response to a rising edge of the clock signal and disables the cascode current mirror and the cascode current source in response to a falling edge of the clock signal. This sequential enablement of the cascode current mirror before the differential input stage improves the unity gain phase margin characteristics of the circuit and the disablement of the cascode current mirror and the cascode current source in response to the falling edge of the clock signal decreases the power consumption requirements of the circuit.Type: GrantFiled: July 29, 1998Date of Patent: April 18, 2000Assignee: Samsung Electronics Co., Ltd.Inventors: Dong-Young Chang, You-Mi Lee, Seung-Hoon Lee, Geun-Soon Kang, Hee-Cheol Choi
