| Abstract: | Most track and hold (T&H) architectures can achieve high speeds however they use a small signal input, meaning that linear behaviour can be assumed for the circuit. Therefore they have a relatively smaller slew rate than a large signal input with the same frequency. For this paper, a T\&H circuit was developed using 130-nanometer CMOS technology, whose purpose is to be able to take samples around the zero crossings of high frequency and large swing sine wave input. This implies that samples are taken when the change in voltage is at its highest (slew-rate). A switched capacitor circuit was used to achieve this, with a complimentary switch configuration. Diode clipping was implemented to remove the excess swing and prevent the MOSFET switches from breaking down from the high input voltage. A cascading inverter driver was also included to supply the MOSFET switches with the extra current to drive the capacitive loads. |
