Abstract
The constant demand for wireless systems pushes engineers and researchers to develop more innovative systems to improve performance. Remarkable improvements have been recently realized on charge-domain SAR ADCs to reach the speed of a few tens of MS/s with medium resolution and low power consumption [1,2]. This has shifted the power bottleneck to the preceding block in a wireless receiver, conventionally the Variable-Gain Amplifier (VGA) that has to charge a few pF of ADC sampling capacitor with rail-to-rail voltage within a few ns with 10b linearity.
