A comprehensive and scalable solution for high-performance switched capacitor amplification is presented. Central to this discussion is the concept of ring amplification. A ring amplifier is a small modular amplifier derived from a ring oscillator that naturally embodies all the essential elements of scalability. It can amplify with accurate rail-to-rail...
It is demonstrated in this paper that it is possible
to synthesize a stochastic flash ADC entirely from Verilog code
and a standard digital library. An analog comparator is introduced
that is constructed from two cross-coupled 3-input digital
NAND gates, and can be described in Verilog. The synthesized
comparators have...
A ones adder is an important circuit block that is required in many varying applications. This work proposes a design that largely relies on passive transmission-gate multiplexers. Many variations are suggested that can inherently generate a thermometer coded output or one-hot encoded output. The proposed structure has area and power...
In this paper the fundamental concept of ring
amplification is introduced and explored. Ring amplifiers enable
efficient amplification in scaled environments, and possess the
benefits of efficient slew-based charging, rapid stabilization,
compression-immunity (inherent rail-to-rail output swing),
and performance that scales with process technology. A basic
operational theory is established, and...
