The Bias Circuit Design of High Gain High Frequency OTALuo, Chi-Chuan 07 August 2008 (has links)
In this thesis, we use the no-capacitor feed-forward (NCFF) compensation scheme which employs a feed-forward path to obtain high gain, high frequency. We use CMFB circuit to adjust the common-mode output voltages and the bias circuit. The CMFB circuit makes the output accurately to the reference voltage.
The circuit was designed and fabricated TSMC 0.35 £gm CMOS process. The dc gain is around 90dB and the cut-off frequency is 1GHz. The supply voltage is ¡Ó1.25V. The output voltage is smaller than 10mV.

Design of a Low Power, High Performance Track-and-Hold Circuit in a 0.18µm CMOS Technology / Design av en lågeffekts högprestanda track-and-hold krets i en 0.18µm CMOS teknologi.Säll, Erik January 2002 (has links)
This master thesis describes the design of a track-and-hold (T&H) circuit with 10bit resolution, 80MS/s and 30MHz bandwidth. It is designed in a 0.18µm CMOS process with a supply voltage of 1.8 Volt. The circuit is supposed to work together with a 10bit pipelined analog to digital converter. A switched capacitor topology is used for the T&H circuit and the amplifier is a folded cascode OTA with regulated cascode. The switches used are of transmission gate type. The thesis presents the design decisions, design phase and the theory needed to understand the design decisions and the considerations in the design phase. The results are based on circuit level SPICE simulations in Cadence with foundry provided BSIM3 transistor models. They show that the circuit has 10bit resolution and 7.6mW power consumption, for the worst-case frequency of 30MHz. The requirements on the dynamic performance are all fulfilled, most of them with large margins.
