2019年8月27日 · VTC（Voltage Transfer Characteristics）曲线： VTC的形状基本上与高于阈值的操作相同。VTC陡峭部分的斜率取决于反向器的亚阈值斜率。 其中涉及到的的四个重要参数：

A digital controlled switched charge pump is used to generate four different current so that this VTC can operate with variable conversion gain. The VTC is designed for time-based ADCs. The simulation results shows that SFDR of the VTC can be greater than 60dB and THD can be lower than -54dB for all working modes.

2020年10月5日 · Abstract: A folding voltage-to-time converter (VTC) is proposed for low-power time-based (TB) flash ADCs performing voltage-to-time-to-digital conversion. Conventional VTCs in TB flash ADCs generate multiple time outputs or have nonlinear conversion gain, resulting in a large power consumption in time-to-digital converters (TDCs) due to power ...

VTC Mathematical Definitions •V OH is the output high level of an inverter V OH = VTC(V OL) •V OL is the output low level of an inverter V OL = VTC(V OH) •V M is the switching threshold V M = V IN = V OUT •V IH is the lowest input voltage for which the output will be ≥the input (worst case ‘1’) dVTC(V IH)/dV IH = -1 •V

Abstract: A folding voltage-to-time converter (VTC) is proposed for time-based ADC. Conventional VTCs suffer serious linearity interference due to its large input range. The proposed VTC adopts a 4x folding architecture, and thus reduce the VTC input range which makes the gain of proposed VTC more larger and linear.

2022年3月21日 · The average gain of the VS-VTC is 6.01 ns/mV while that of the CS-VTC is 1.37 ns/mV. It should be noted that the gain of CS-VTC can be varied by adjusting either the current of the cascode current mirror or the integration capacitor.

2020年2月26日 · In this paper, we proposed a Darlington pair- and source biasing-based high speed, secure, and reliable voltage to time converter (VTC). It is a compact, high-speed design and gives high conversion gain. The source biasing …

2022年3月25日 · 提高电源电压VDD可以提高CMOS电路的 直流噪声容限 （因为是静态特性）。 静态特性：输入电平在0、1之间跳变时，电路状态的变化。 输入特性：从反相器输入端看进去的输入电压与输入电流的关系。 正常情况下输入特性的区域是中间电流非常小的区域。 输出特性：从反相器输出端看进去的输出电压与输出电流的关系。 由于Vin的高电平一般就是VDD，所以VDD改变时，影响了RON的大小。 动态特性：：动态转换过程中的特性. 文章浏览阅读4.1k次，点 …

From the detailed analysis of VTC characteristics it can be observed that, CMOS inverter has a very narrow transition zone. Therefore, high gain can be achieved when both NMOS and PMOS are simultaneously ON and operated in saturation.
